Stichodactyla gigantea, commonly known as the giant carpet anemone,[2] is a species of sea anemone that lives in the Indo-Pacific area. It can be kept in an aquarium but is a very challenging species to keep alive and healthy for more than 3–5 years.


Stichodactyla gigantea has a diameter that is usually no larger than 50 centimetres (1.6 ft) and a maximum of 80 centimetres (2.6 ft).[3] It can appear in a number of colors, commonly brown or greenish and rarely a striking purple or pink, deep blue, or bright green.[4] A healthy S. gigantea will possess tentacles that are extremely sticky to the touch, with firm adherence to surfaces.[4]


S. gigantea resides on shallow seagrass beds or sand flats around 8 centimetres (3.1 in) deep (at low tide).[5] Most anemones are treated as sessile, but the ones inhabited by anemonefish are in fact motile.[4] Zooxanthellae are obligate symbionts within the anemone.

S. gigantea hosts 7 different species of anemonefish

Juvenile Dascyllus trimaculatus also associate with S. gigantea.[4]

Aquarium trade[edit]

S. gigantea is uncommon in the aquarium trade.[6] Though smaller in size than other carpet anemone species, it is significantly more delicate, and requires a large, mature reef aquarium. Like all sea anemones in captivity that have a symbiotic, mutualistic relationship with anemonefish, S. gigantea requires intense aquarium lighting, impeccable water quality, and stable parameters.[6] It is prone to shipping stress and bacterial infections during transit.[6] Due to these factors, many hobbyists advocate quarantining this anemone and treating with antibiotics such as Ciprofloxacin or Septra for a minimum of one week before acclimating it to the main tank.[7]
