Red Giant Carpet Anemone is a red colour form of Stichodactyla gigantea, one of the true giant carpet anemones kept by experienced marine aquarists. The colour label is not part of the Latin name; the care anchor is the species Stichodactyla gigantea.
This is a specialist reef animal for mature systems with intense lighting, stable salinity and carefully protected flow. It has a strong sting, can move if unsettled and needs open placement away from corals that could be damaged.

Plan the aquarium around the anemone before adding it. Use strong reef lighting, excellent biological filtration, stable salinity and guarded pump intakes. Leave clear space around the oral disc because nearby corals and small animals can be stung.
Natural related options include Green Giant Carpet Anemone, Heteractis magnifica Anemone, Rock Flower Anemone, Clown Anemonefish and Black Ocellaris Clownfish. Choose tank mates with caution and avoid cramped mixed-coral placement around the anemone.
Is the red colour part of the scientific name? No. The species anchor is Stichodactyla gigantea; red describes the colour form offered in this listing.
Is this suitable for beginners? No. Giant carpet anemones need mature reef systems, strong lighting, stable water and experienced placement.
