Overview
Frogspawn coral (Euphyllia paradivisa, family Euphylliidae) is a large-polyp stony (LPS) coral from Indo-Pacific reef slopes. Numerous tentacles with bulbous, rounded tips emerge from a branching skeleton, resembling a mass of frog eggs and giving the coral its name. It shows greens, golds, and purples, and the tentacles sway beautifully in the current. It is relatively easy to keep under low to moderate lighting and gentle low to moderate flow. Avoid strong direct current, which damages the tentacles, and intense light, which causes fading. Its long sweeper tentacles aggressively attack nearby corals, so ample spacing is essential. Feeding once or twice weekly promotes color and growth. It propagates by skeletal division and is a popular Euphyllia alongside hammer and torch corals.

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...
