Overview
Frogspawn coral (Euphyllia divisa, family Euphylliidae) takes its name from the branched, rounded tentacle tips that resemble amphibian egg masses. Native to reef slopes of Indo-Pacific islands, it occurs in branching and wall-type colony forms, with tentacles in green, tan, and gold fluorescent hues. Alongside torch and hammer coral, it forms the celebrated Euphyllia trio prized in reef aquaria. Moderate lighting (150–250 PAR) and gentle indirect flow are optimal; its potent sweeper tentacles demand ample spacing from neighboring corals. Stable alkalinity and temperature, supplemented by occasional target feeding, ensure robust long-term growth.

Natural Spawning and Breeding in LPS Corals | Key Points for Juvenile Coral Rearing and Parental Stock Selection
Natural spawning in LPS (Large Polyp Stony) corals is a biological event triggered by multiple interacting environmental factors. The primary driver is photoperiod: as day length extends from spring into early summer, gonadal development in individual colonies accelerates. Most LPS species reach their spawning season between April and July, with decreasing nighttime illumination and lunar cycles serving as the final spawning triggers...
