Aquatic plants are used to give the aquarium a natural appearance, oxygenate the water, and provide habitat for fish, especially fry (babies) and for invertebrates. Some aquarium fish and invertebrates also eat live plants. Hobby aquarists use aquatic plants for aquascaping.
Marine algae are also included in this list for convenience, despite the fact that many species are technically classified as protists, not plants.
Brown macroalgae
Brown macroalgae are sometimes seasonally available in the aquarium trade and under suitable conditions, will grow quite prolifically. They possess the pigment Fucoxanthin which gives them their coloration ranging from yellow to dark brown. A few are desirable yet many are pests with some species being rather difficult to remove, often making their way into aquariums on live rock.[1]
Common name | Image | Taxonomy | Care Level | Growth rate | Nutrient uptake | Lighting | Waterflow | Palatable | Description | Max size |
---|---|---|---|---|---|---|---|---|---|---|
Brazilian brown alga | Canistrocarpus cervicornis | Easy[2] | Moderate[3] | Good[3] | Moderate-High[3] | Moderate-High[3] | Somewhat[3] | This very hardy algae thrives in shallower waters. It features flat, spiraling blades which may or may not feature iridescence and vary from olive brown to gold in coloration. Though it does not grow very quickly, pruning is necessary to maintain an individual. Once known as Dictyota cervicornis.[2][4] | 10 in (25.4 cm)[4] | |
False sargasso | ![]() | Cystoseira sp. | Moderate[5] | Slow[5] | Fair[5] | Moderate-High[5] | Moderate-High[5] | No[5] | A rare algae in the aquarium trade, commonly confused with Sargassum which has flat blades while False Sargasso has tight toothlike appendages. It also has lower nutrient requirements due to its smaller size. Characterized by its stiff stipes, the outermost of which support pneumatocysts, and its light brown coloration.[5] | 18 in (45.7 cm)[5] |
Iridescent algae | ![]() | Dictyota sp. | Moderate[3] | Moderate[3] | Good[3] | Moderate-High[3] | Moderate-High[3] | Somewhat[3] | The appearance of species within this genus varies greatly. Some display blue iridescence while others are a dull olive color. Larger bladed species are desirable as smaller ones can become invasive. However, all grow in clumps (on hard surfaces or as epiphytes) and are quite delicate, being known to clog pumps and filters. In the wild, the algae is abundant in the intertidal zone and shallow reef flats. Manual removal and clean up crew, like Longnose decorator crabs, can be used to combat this algae[3][6] | 12 in (30.5 cm)[3] |
Encrusting fan-leaf algae | ![]() | Lobophora sp. | Moderate[7] | Moderate[7] | Good[7] | Low-Moderate[7] | Low-Moderate[7] | Somewhat[7] | This algae is very similar to Scroll algae although it is not calcified, being rubbery to the touch. It comes in various shades of brown and green and because it comes from deep waters, it requires little lighting. Rarely does it enter aquariums, which usually occurs when it hitchhikes on live rock. Surprisingly, the algae has a rhizoidal holdfast despite seeming to primarily encrust.[7][8] | 10 in (25.4 cm)[7] |
Scroll algae | ![]() ![]() | Padina sp. | Expert[9] | Slow[9] | Fair[9] | Moderate-High[9] | Moderate-High[9] | No[9] | Also known as Potato algae, it is quite desirable given its beauty, which may be enhanced if Coralline algae is allowed to encrust its surface. The algae itself features green to brown coloration and grows in the shape of a rounded or split, irregular cup with concentric rings. Its single holdfast should be affixed to a hard bottom and calcium supplementation is required for growth as it is calcified.[9] | 6 in (15.2 cm)[9] |
White scroll algae | ![]() | Padina sanctae-crucis | Expert[9] | Slow[9] | Fair[9] | Moderate-High[9] | Moderate-High[9] | No[9] | This species of algae, also known as Peacock algae, is the most common of the Padina genus in the aquarium trade. It often enters aquariums on live rock.[9][10] | ~6 in (15.2 cm)[10] |
Brown algae | Polycladia myrica | Moderate[5] | Slow[5] | Fair[5] | Moderate-High[5] | Moderate-High[5] | No[5] | This algae makes seasonal appearances in the aquarium trade and originates from The Bahamas and Florida. Once known as Cystoseira myrica.[5][11] | ||
Gulfweed | ![]() | Sargassum filipendula | Expert[12] | This algae is naturally found on both sides of the Atlantic Ocean, and serves as habitat for a variety of marine animals. Because it features pneumatocysts, individual specimens will float without a holdfast. Additionally, it should only be attempted by advanced aquarists. Also known as Sargassum weed.[12][13] | 79 in (200.7 cm)[14] | |||||
White-vein sargasso | ![]() | Sargassum hystrix | Expert[15] | Slow[15] | Fair[15] | High[15] | Moderate-High[15] | Not really[15] | This species is tolerable of cooler temperatures than most other macroalgae. It attaches itself to hard surfaces, using a holdfast, in shallow, turbulent environments and keeps itself upright with a sturdy stipe. The algae grows large, brown blades and a variety known as Sargassum hystrix buxifolium exists, lacking a white-colored mid rib.[15] | 24 in (61.0 cm)[15] |
Deep-toothed gulfweed | ![]() | Sargassum platycarpum | Expert[16] | Slow[16] | Fair[16] | High[16] | Moderate-High[16] | Not really[16] | This species extends serrated, golden blades from its thick stipes along with pneumatocysts to hold it upright. Individuals may also grow a holdfast and the ones that do are most suitable for aquariums as they are capable of anchoring themselves. It is often found on live rock and should frequently be pruned.[16] | 30 in (76.2 cm)[16] |
Leafy flat-blade algae | Stypopodium zonale | Moderate[17] | Moderate[17] | This species of algae produces highly toxic extracts that are harmless toward smaller grazers including amphipods and polychaetes yet are capable of killing herbivorous reef fish. Death occurs within 10 hours of the algae's introduction to a well-aerated aquarium during which the fish will attempt to jump out.[18] | 8 in (20.3 cm)[19] | |||||
Pyramid seaweed | ![]() ![]() | Turbinaria sp. | Expert[20] | Slow[20] | Fair[20] | High[20] | Moderate-High[20] | To some fish[20] | This tough macroalgae is rubbery to the touch, features toothed, triangular blades, and anchors itself to substrate using a holdfast. It is quite variable, with some individuals growing in short, tight clusters while others feature a tall stipe. It prefers to be placed near the top of an aquarium, becoming quite hardy in the presence of strong flow and lighting.[20] | 2 in (5.1 cm)[20] |

Green macroalgae are extremely diverse and abundant, coming in a wide variety of shapes. They possess the pigment Chlorophyll which gives them their coloration ranging from bright green to yellow or dark jade. Reproduction via fragmentation or the releasing of spores are utilized by this macroalgae group. The second option, which is used by the genus, Caulerpa, can be quite problematic in an aquarium.[21] Some species of green macroalgae have greater ease surviving in high nutrient environments or inadequate water parameters than other kinds of macroalgae and are generally the most suitable for nutrient removal due to their rapid growth rates.[22]
Common name | Image | Taxonomy | Care Level | Growth rate | Nutrient uptake | Lighting | Waterflow | Palatable | Description | Max size |
---|---|---|---|---|---|---|---|---|---|---|
Mermaid's wine glass | ![]() | Acetabularia sp. | Moderate[23] | Slow[23] | Poor[23] | High[23] | Low[23] | Yes[23] | A beautiful and interesting genus of algae which, unfortunately, tends to be short-lived in aquariums. It grows a disc-like appendage which is more pronounced in certain species, is easily broken when removed from water, and may be removed to start a new colony. A hard surface to attach to as well as calcium supplementation are required to grow the calcified algae.[23] | 4 in (10.2 cm)[23] |
Basket weave | Anadyomene sp. | Moderate[24] | Slow[24] | Poor[24] | Moderate[24] | Moderate[24] | To some fish[24] | Most specimens make their way into aquariums through live rock and amongst calcareous algae from the wild, staying small in captivity. It possesses rigid, variable, irregularly shaped blades which are characterized by their patterned veins. Anadyomene saldanhae and Anadyomene stellata are the most popular species of this genus.[24] | 10 in (25.4 cm)[24] | |
Fan weed | ![]() | Avrainvillea sp. | This species of algae grows a central stalk supporting a single, fan-shaped blade.[25] | |||||||
Green sea sausage seaweed | ![]() | Bornetella nitida | Moderate[26] | Moderate[26] | Low[26] | Not really[26] | In the wild, this algae grows in shallow water environments such as tide pools and on tumbling beach rocks. It features firm, yet elastic fronds which grow vertically and take on a reddish coloration during their growth stage. Provided with an environment suitable for soft corals, the algae will grow in its most desirable shape.[26] | 2 in (5.1 cm)[26] | ||
Spherical turtle shell | ![]() | Bornetella sphaerica | Moderate[27] | Moderate[27] | Low[27] | Not really[27] | In the wild, this algae grows in shallow water environments such as tide pools and on tumbling beach rocks. It features firm, yet elastic fronds which take on a reddish coloration during their growth stage. Provided with an environment suitable for soft corals, the algae will grow in its most desirable shape.[27] | 2 in (5.1 cm)[27] | ||
Bryopsis | ![]() | Bryopsis sp. | Easy[28] | Fast[28][29] | Somewhat[30] | This algae is usually seen as a nuisance though it may be desirable in Macroalgae tanks. Though it is rarely sold on its own, it often enters aquariums through live rock and is hard to eradicate due to its firm grip on rockwork. Its coarse composition aids in accumulating detritus from which it can derive nutrients. Eradication can be achieved through the use of grazers (including several crabs, mollusks, and sea urchins), manual removal, light starvation, and nutrient reduction. Elevated magnesium may hinder the growth of the algae but can be dangerous to invertebrates.[28][29][30][6] | ||||
Sea fern | ![]() | Bryopsis pennata | Easy[28] | Fast[28][29] | Somewhat[30] | One of the most difficult species of algae to eradicate in the hobby. This algae is characterized by its pronounced midrib and mat-like rhizoids. Compared to Bryopsis plumosa, Bryopsis pennata features more irregular and sparsely branching fronds.[6] | 4 in (10.2 cm)[31] | |||
Hen pen | ![]() | Bryopsis plumosa | Easy[28] | Fast[28][29] | Somewhat[30] | One of the most difficult species of algae to eradicate in the hobby. This algae is characterized by its pronounced midrib and mat-like rhizoids. Compared to Bryopsis pennata, Bryopsis plumosa features more symmetrical and densely branching fronds.[6] | 4 in (10.2 cm)[32] | |||
Giant feather algae | Caulerpa asmeadii | Easy[33] | Moderate[33] | Good[33] | Moderate[33] | Low-Moderate[33] | Somewhat[33] | This is a large species of Caulerpa although unlike its relatives, it won't outgrow its environment as it is slow-growing. It features a thick rhizome which should be pinched when pruned to reduce the amount of pollutants released. Younger individuals may be confused with Caulerpa sertularioides, which inhabits shallower habitats and both may be sold as Feather algae.[33] | 14 in (35.6 cm)[33] | |
Sea mustard | ![]() ![]() | Caulerpa brachypus | Easy[34] | Fast[34] | Good[34] | Moderate-High[34] | Moderate[34] | Somewhat[34] | Also known as Mini caulerpa. Though this uncommon species of Caulerpa is more palatable than Caulerpa prolifera, herbivorous fish tend not to consume it. It will attach itself to both rocks and sand substrates with rhizoids, is a good refugium addition for nutrient export and housing microinvertebrates, and requires regular pruning.[35][34][36] | 1 in (2.5 cm)[37] |
Umbrella algae | ![]() | Caulerpa chemnitzia | Easy[38] | Fast[38] | Excellent[38] | Moderate[38] | Moderate-High[38] | Not really[38] | Rarely seen in the hobby and can be found in dim habitats in the wild. The algae is excellent at stripping a tank of nutrients so it must be carefully monitored. Two varieties exist, one with smooth, round blades and the other with concave blades. Was known as Caulerpa peltata and also may be called Saucer algae and Mushroom algae.[39][38][40] | 6 in (15.2 cm)[33] |
Zipper algae | ![]() | Caulerpa cupressoides | Easy[41] | Slow[41] | Fair[41] | Moderate-High[41] | Moderate[41] | No[41] | This interesting and undemanding species of Caulerpa prefers to grow on sand, however it can grow off of harder surfaces. The algae features long, stiff stipes bordered by notched blades and is naturally found growing in shallow-water seagrass meadows. Seahorses will readily use its stipes as hitching posts. Also known as Cactus caulerpa.[41][42][43] | 8 in (20.3 cm)[41] |
Banana algae | ![]() | Caulerpa cylindracea | Easy[44] | Fast[44] | Excellent[44] | Moderate-High[44] | Moderate-High[44] | No[44] | This tall algae features cylindrical blades, making it resemble a cluster of bananas, as well as a dark green coloration. It is excellent at stripping a tank of nutrients so its size must be limited. Though it is mostly inedible, some fish may nip at its holdfast.[44] | 6 in (15.2 cm)[44] |
Razor algae | Caulerpa floridana | Easy[45][46] | Moderate[46] | This algae, also known as Florida caulerpa, originates from shallow environments such as lagoons and bays and enters aquariums through Caribbean and Floridian live rock. It is not very popular in the hobby.[46] | ||||||
Small sea grapes | ![]() | Caulerpa lentillifera | Moderate[47] | Fast[47] | High[48] | Moderate[48] | Yes[48] | This species of Caulerpa prefers to grow on rockwork though it may venture out onto the substrate. Under strong lighting, it will grow dense blades, resembling clusters of grapes. Additionally, it is known to be edible to humans and is also called Green caviar, Latok, and Umibudo.[47][48] | 6 in (15.2 cm)[49] | |
Fern algae | ![]() | Caulerpa mexicana | Easy[50] | Moderate[50] | Good[50] | Moderate[50] | Low-Moderate[50] | Somewhat to fish[50] | This species of tight-bladed Caulerpa can grow on hard surfaces as well as sandy and muddy substrates. In turbulent surroundings, it grows somewhat compact and in calmer surroundings, it grows taller. Its adaptability to lighting requirements allows it to grow in environments without direct lighting amongst other algae (such as under ledges).[50] | 8 in (20.3 cm)[50] |
Coin Caulerpa | Caulerpa nummularia | This algae can be maintained in a refugium with constant exposure to light and regular pruning every few weeks. It uses a rhizome to anchor to rocks and substrate and can be very difficult to remove once established.[51] | ≤1 cm (0.4 in)[52] | |||||||
Palm tree algae | ![]() ![]() | Caulerpa paspaloides | Easy[53] | Moderate[53] | Excellent[53] | Moderate[53] | Low-Moderate[53] | Somewhat[53] | This species of Caulerpa is a good nutrient export choice as it pollutes aquariums less often than its relatives and is fast growing. It should be pruned regularly as its fine structure captures undesirable substances. Under more intense lighting, the algae's palm-shaped blades will grow more compact and triangular in addition to taking on a darker shade of green.[53] | 12 in (30.5 cm)[53] |
Bladed sand moss | ![]() | Caulerpa prolifera | Easy[54] | Fast[54] | Excellent[54] | Moderate[54] | Low-Moderate[54] | Somewhat[54] | Bladed sand moss is well-suited for aquariums as it grows slower than other members of its genus and is easily pruned. It desires sandy substrates, inhabiting seagrass meadows in the wild, and will grow wider blades in turbulent water and taller, thinner blades in calmer environments. Out of all the Caulerpa species that are commercially available, this one is the most popular and widespread, commonly used to cover sand beds in marine planted aquariums.[54][55] | 6 in (15.2 cm)[54] |
Coarse sea grapes | ![]() ![]() | Caulerpa racemosa | Easy[56] | Fast[56] | Excellent[56] | Moderate-High[56] | Moderate-High[56] | Somewhat[56] | Unlike other species of Caulerpa, this one grows round, clustered blades. It is notorious for releasing spores and stripping tanks of available nutrients as well as its invasively rapid growth (having given the entire Caulerpa genus a bad rap). As such, it must be carefully monitored and pruned. Many varieties of this algae exist worldwide which are highly varied and inhabit shallow-water environments.[56][6] | 8 in (20.3 cm)[56] |
Sawtooth algae | ![]() | Caulerpa serrulata | Easy[57] | Moderate[57] | Good[57] | Moderate[57] | Low-Moderate[57] | Somewhat[57] | This smaller sized, hardy species of algae is often available and put in refugiums for nutrient export or used to create thick bushes in the foreground of an aquarium. It originates from shallow habitats where it prefers to grow on small rocky objects and its stiff nature makes it unappetizing to most organisms. Weaker lighting will lessen the jaggedness of its twisted blades.[57][58] | 5 in (12.7 cm)[57] |
Green feather algae | ![]() | Caulerpa sertularioides | Easy[59] | Fast[59] | Excellent[59] | Moderate[59] | Low-Moderate[59] | Yes[59] | This shallow-water Caulerpa species features fronds with rounded tips. It is very popular among hobbyists although it grows quickly, easily taking over aquariums. However, it is a great choice for refugiums considering how many fish and invertebrates enjoy eating it. The algae prefers to grow on hard surfaces, yet its adaptability allows it to also grow on the sand bed and climb aquarium walls.[59] | 8 in (20.3 cm)[59] |
Killer algae | ![]() | Caulerpa taxifolia | Easy[60] | Fast[60] | Excellent[60] | Moderate[60] | Low-Moderate[60] | No[60] | Also known as Fern algae and Feather plant, this algae can become quite invasive in the wild as it is able to survive in a wide range of temperatures and grows rapidly. For this reason, it is rare within the United States. It appears similar to Caulerpa mexicana although its dark-green fronds are more uniform and spaced further apart. The algae will spread on both rocks and sand.[60][61] | 10 in (25.4 cm)[60] |
Fluffy green seaweed | ![]() | Caulerpa verticillata | Easy[62] | Fast[63] | Low-High[63] | Though this is a rather short species of the Caulerpa genus, Fluffy green seaweed or Fuzzy caulerpa can grow extremely quickly, even on walls. As such, it is only suitable for marine planted aquariums. Regular pruning should be performed by twirling the algae's blades around one's fingers, separating it's holdfast from hard surfaces. Amphipods and copepods enjoy living within the algae.[63][64] | 5.9 in (15.0 cm)[62] | |||
Spaghetti algae | ![]() ![]() | Chaetomorpha sp. | Easy[65] | Fast[65] | Excellent[65] | Low-High[65] | Moderate[65] | Not really[65] | Also called Chaeto, this algae grows as a tangled mass of green filaments and originates from shallow, nutrient rich environments. It is incredibly popular with aquarists since it serves as habitat for microinvertebrates (such as amphipods and copepods) and rapidly consumes excess nutrients (though care must be taken to replenish these nutrients such as iron, nitrates, and phosphates). For this reason, it is often kept in a refugium where it can either be tumbled or left to float. Despite being hardy and easy to grow, care must be taken to meet the different environmental requirements of the different species of Spaghetti algae.[65][66][67] | 24 in (61.0 cm) mound[65] |
Tall hair alga | ![]() | Chaetomorpha aerea | Easy[68] | Fast[69] | Excellent[69] | Moderate[68] | Moderate[68] | Yes[68] | Once known as Chaetomorpha crassa. It is rare example of a hair algae species suitable for marine aquariums, being an excellent refugium addition. In captivity, the stiff, filamentous algae serves as habitat for microinvertebrates, provides nutrient export, and can be fed to herbivores, though it should ideally be tumbled. Naturally, this algae is found in the intertidal zone.[68] | 6 in (15.2 cm) mound[68] |
Floating chaeto | ![]() ![]() | Chaetomorpha linum | Easy[70] | Fast[70] | Excellent[70] | Moderate-High[70] | Moderate[70] | No[70] | Also known as Spaghetti algae. This stable, greenish algae is composed of unbranched, tangled filaments, finer and more flexible than those of Chaetomorpha spiralis. It is excellent at nutrient export, but care must be taken to replenish said nutrients in a system containing Chaetomorpha linum, such as nitrate, phosphate, Magnesium, Iodine, and Iron. Additionally, herbivorous fish cannot digest this algae, though they might attempt to eat it.[70][71] | 16 in (40.6 cm)[70] |
Curly Chaeto | ![]() | Chaetomorpha spiralis | Moderate[72] | Fast[72] | Excellent[73] | High[72] | Moderate[72] | Also known as Spaghetti algae and Green hair algae (not Derbesia). This hardy algae is composed of clumped, long filaments, thicker and more brittle than those of Chaetomorpha linum. It is an excellent addition for refugiums, serving as habitat for microinvertebrates and providing nutrient export.[72][71] | 20 in (50.8 cm)[74] | |
Green tide alga | ![]() | Cladophora coelothrix | High[13] | This algae is composed of compacted filaments, forming a sphere. It does best in cooler water.[13] | 20 in (50.8 cm)[75] | |||||
Toadstool algae | ![]() | Cladophora prolifera | Easy[45] | Slow[45] | Poor[76] | Moderate-High[76] | Low-High[76] | Somewhat[76] | This species of shallow-water algae grows in clumps on rocks and rubble, featuring rigid, finely branched filaments. Many aquarists believe it is a nuisance since it will become hard to remove after establishing itself. However, microinvertebrates enjoy living within the algae, such as starfish. May also be called Green bush, Moss ball, and Sea hair.[77][45][78] | 20 in (50.8 cm)[79] |
Green wiry algae | ![]() ![]() | Cladophoropsis sp. | Slow[6] | Yes[6] | This low-lying algae creeps along rocks and can be difficult to remove. Often, it is found on frags and live rock. It is known to persist in low-nutrient environments. Also known as Bob Ross algae.[6][80] | |||||
Turtleweed | ![]() ![]() | Chlorodesmis sp. | Expert[81] | Moderate[81] | Good[81] | High[81] | Moderate-High[81] | No[81] | Also known as Maiden's hair plant, this popular, stringy algae is often mistaken for hair algae and enters the aquarium trade on live rock and coral. It is toxic, making it inedible and capable of effecting coral growth, though microinvertebrates enjoy living within the algae such as amphipods and copepods. If the blades of the algae turn white, they should be removed.[82][81][83] | 8 in (20.3 cm)[81] |
Dead man's fingers | ![]() ![]() | Codium sp. | Easy[84] | Slow[84] | Fair[84] | Moderate-High[84] | High[84] | No[84] | Some forms of this algae feature a single holdfast with multiple irregular branches and others encrust surfaces taking on a blob-like shape. They should be placed on hard surfaces and kept in water temperatures under 80 °F (26.7 °C). Though the main structure of Dead man's fingers is inedible, some fish may graze on the fuzzy filaments that cover its surface.[84][85][86] | 12 in (30.5 cm)[84] |
Green fleece | ![]() | Codium decorticatum | Easy[87] | Slow[87] | High[87] | Low[87] | Not really[87] | This desirable algae features thick, fingerlike protrusions that provide habitat for microcrustaceans and can break apart if disturbed. Though it floats, it can be attached to solid surfaces with superglue. In nature, it is distributed worldwide in shallow waters, though it is rare in the aquarium hobby.[87] | 12 in (30.5 cm)[87] | |
Tufted joint algae | ![]() | Cymopolia barbata | Moderate[88] | Slow[88] | Fair[88] | High[88] | Moderate-High[88] | Not really[88] | This species of prehistoric-looking algae is rarely available although it may enter aquariums through live rock. It is quite interesting, but requires calcium supplementation as it is calcified. Pieces of the algae may be clipped and fed to Tangs and Rabbitfish. Also known as Palm tree algae.[88][89] | 12 in (30.5 cm)[88] |
Usugasane | Cymopolia vanbosseae | Easy[90] | Moderate[90] | Moderate[90] | In the wild, this algae grows in shallow water environments. It is calcified and its base is white due to the lack of Chlorophyll. In the aquarium, this algae will deteriorate if other algae is allowed to grow on its surface and should be exposed to fluorescent lighting for dense frond growth (though the algae can be grown under LED lighting).[90] | 2 in (5.1 cm)[90] | ||||
Green hair algae | ![]() ![]() | Derbesia sp. | Fast[6] | Excellent[91] | High[91] | Yes[6] | Green hair algae is the desired algae in algae scrubbers for nutrient export and the rearing of microinvertebrates. Outside scrubbers, it is a pest and is distinguished from similar algae by its lack of a root system, delicate nature, and fine texture. Removal is simple as it can be pulled or scrubbed off rockwork and sifted from sand and is highly palatable to a variety of herbivores. Proper water quality and low nutrient levels also discourage the growth of this algae as does lighting that is less red.[6][91] | |||
Green bubble weed | ![]() | Dictyosphaeria cavernosa | Various[92] | Somewhat[92] | In the wild, this green to bluish algae thrives in rocky crevices where detritus can accumulate. It will tolerate a variety of lighting intensities and survive in aquariums with low nutrient levels. The algae is made up of easily-seen, bubble shaped cells which, when ruptured, release new cells that will settle throughout an aquarium system.[92][93] | 5 in (12.7 cm)[93] | ||||
Isosugina | ![]() | Halicoryne wrightii | Moderate[94] | Low[94] | Yes[94] | In the wild, this algae grows in shallow water environments such as tide pools and on tumbling beach rocks. The algae's yellow-green coloration is a result of limestone deposits on its fronds which requires specific Carbonate hardness levels to form. This algae will become weakened if other algae is allowed to grow on its surface.[94] | 2 in (5.1 cm)[94] | |||
Large leaf watercress algae | ![]() | Halimeda discoidea | Easy[95] | Moderate[95] | Fair[95] | Moderate-High[95] | Moderate[95] | Somewhat[95] | Out of all the Halimeda species, this one possesses the largest segments and unlike its relatives, only grows on hard surfaces. It requires calcium supplementation as it is calcified, making it a good food for grazers (such as Tangs) as it helps keep their digestive tracts free of blockages. Also known as Money plant and Rosette halimeda.[95][96][97] | 10 in (25.4 cm)[95] |
Three finger leaf algae | ![]() ![]() | Halimeda incrassata | Easy[98] | Moderate[98] | Fair[98] | Moderate-High[98] | Moderate[98] | No[98] | Also known as Money plant, this algae either grows in clumps or forms several branches. It requires calcium supplementation as it is calcified (making it a good food for clearing blockages in the digestive tracts of grazers) and a sand bed at least 4 in (10.2 cm) deep. While generally small, this algae will rapidly reproduce under favorable conditions, sprouting new individuals near its base.[98][99] | 8 in (20.3 cm)[98] |
Jointed-stalk algae | ![]() | Halimeda monile | Slow[100] | Fair[100] | Low-High[100] | No[100] | This algae is ideal for use in aquascaping as it is inedible. Though it can be housed under a wide range of lighting strengths, it grows best under Moderate-High lighting and prefers to grow in finer substrates. It also requires calcium supplementation as it is calcified. Individuals will appear stressed when they attempt to spread, using the majority of their energy to produce new growth.[100] | 8 in (20.3 cm)[101] | ||
Prickly pear | ![]() | Halimeda opuntia | Easy[102] | Moderate[102] | Fair[102] | Moderate-High[102] | Moderate[102] | No[102] | This algae forms large mounds of tight segments and attaches itself to rocks and sand using several holdfasts.

Most mangroves that end up in the aquarium trade are either collected as seeds or grown on land.[242] Their leaves should be exposed to the air, well beyond the surface of the water, and be sprayed with freshwater regularly to prevent salt buildup. They also require intense lighting and a layer of substrate, not too shallow as to let the tree topple over and not too fine which would make parts of the sandbed to go anaerobic.[243]
