The Frogspawn coral is a moderately hardy, flowing large polyp stony (LPS) coral featuring multi-tipped, bubble-like tentacles that resemble clusters of frog eggs. Popular in reef aquariums for its hypnotic movement, it thrives in moderate light and gentle-to-medium water flow, making it an excellent choice for beginners stepping into stony corals.
Tank Requirements
Lighting: Moderate (30–150 PAR); low light promotes polyp expansion, while too much light causes bleaching.
Water Flow: Moderate and indirect; enough to keep tentacles waving without tearing the delicate tissue against its skeleton.
Temperature: 72°F – 78°F (22°C – 26°C).
Salinity (Specific Gravity): 1.023 – 1.025.
pH Range: 8.1 – 8.4.
Care and Feeding
Placement: Low-to-middle sections of the aquarium secured to a rock structure.
Diet: Photosynthetic via zooxanthellae, but benefits greatly from weekly target feeding of mysis shrimp or specialized coral pellets.
Temperament: Semi-aggressive; extends long, stinging sweeper tentacles at night and must be kept spaced several inches away from non-Euphyllia corals.
