Euphyllia spp.
Reef-dwelling corals with extended polyps. Hammer corals feature hammer-shaped tentacles, while torch corals display flame-like polyps. Both responsive to water flow and lighting, making them beginner-friendly for marine aquaria.
Euphyllia (family Euphylliidae) is a group of large-polyp stony (LPS) corals from Indo-Pacific reef slopes, popularly distinguished by tentacle shape as hammer, torch, and frogspawn corals. Their long, inflated tentacles sway beautifully in the current, showing greens, golds, pinks, and purples. They are 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. They wield long sweeper tentacles that aggressively attack nearby corals, so ample spacing is essential. Feeding once or twice weekly promotes color and growth. They propagate by skeletal division and are among the most popular corals in the reef hobby.
