Condylactis gigantea (Green) is a popular and visually impressive sea anemone known for its large, vibrant green tentacles and robust nature. This species is well-suited to marine aquariums and can be kept in reef or fish-only setups with appropriate care.
Feeding: While Condylactis gigantea can derive nutrients from photosynthesis via its symbiotic zooxanthellae, it benefits greatly from supplemental feeding. Offer meaty foods such as mysis shrimp, chopped seafood, or specialised anemone pellets 1-2 times per week to promote healthy growth.
Compatibility and Reef Safety: This anemone is generally reef safe but should be kept with caution around small or delicate corals, as its tentacles can sting. It is compatible with many fish species, including clownfish, which may host in it. Avoid housing with aggressive or large predatory fish that may harm the anemone.
Tank Requirements: A minimum tank size of 75 litres (20 gallons) is recommended to provide adequate space and stable water parameters. Moderate lighting is preferred to support its photosynthetic needs without causing stress. Moderate water flow is ideal, ensuring the anemone’s tentacles gently sway without being blasted.
Placement: Place Condylactis gigantea on a stable rock or sandy substrate where it can attach securely. Avoid areas with strong direct flow or intense lighting. It may move occasionally, so ensure it cannot reach corals you wish to protect.
Origin and Size: Origin is not provided. This species can reach a diameter of up to 30 cm in captivity, depending on care and tank conditions.
