The Heteractis crispa (White) is a large, visually impressive sea anemone known for its long, slender tentacles and vibrant white coloration. This species is a captivating addition to mature marine aquariums, offering both aesthetic appeal and interesting symbiotic relationships with certain clownfish species.
Care Level: Moderate to advanced. This anemone requires stable water parameters and a well-established tank.
Feeding: While Heteractis crispa can derive nutrition from photosynthesis via its symbiotic zooxanthellae, it benefits greatly from supplemental feeding. Offer meaty foods such as mysis shrimp, brine shrimp, or finely chopped seafood 1-2 times per week to promote health and growth.
Compatibility & Reef Safety: Generally reef safe with caution. It can coexist with many reef inhabitants but may sting nearby corals or invertebrates if tentacles come into contact. Suitable tank mates include compatible clownfish species that may host within its tentacles.
Lighting & Water Flow: Requires moderate to high lighting to support its photosynthetic needs. Moderate water flow is ideal to ensure tentacles gently sway without causing damage or stress.
Placement: Place on a stable rock or substrate area with enough space to expand fully without touching other corals or anemones. Avoid areas with very strong currents or direct blast from powerheads.
Tank Requirements: A minimum tank size of 120 litres (approximately 30 gallons) is recommended to provide sufficient space and stable water conditions.
Origin: Not Provided.
Maximum Size: Can reach up to 30 cm in diameter when fully expanded.
