Hammers, Torches, and Frogspawn do not require as much light as some other corals. It can be kept under normal output fluorescents without much difficulty. Hammer corals may extend more readily under subdued lighting, however it may display more attractive colors when placed under stronger lighting. Generally speaking though, these corals maintain consistent coloration and the risks of overexposing the corals to high light outweigh the benefits.

Moderate to strong water movement is recommended. One of the main draws to this type of LPS coral is how it sways in the current. Water flow is both healthy for the Hammer and is pleasing aesthetically.

Like most coral, Euphyllia rely to a large extent on photosynthesis, however, they also benefit from direct feeding. Hammers, torches, and frogspawn do not seem to aggressively feed like other LPS, so finding the right food can be a challenge. We have had some good luck with a dry pellet food called Sustainable Aquatics Hatchery Diet. It is intended for use with small fish, but we have tried feeding it to corals like the Euphyllias, which tend to be finicky eaters, with good results.

Euphyllia are one of the corals known for extending long sweeper tentacles. Sweeper tentacles are often used as a means of defense against other encroaching coral colonies. Their white tips contain a high concentration of nematcysts that can damage more delicate tank mates. Most of the time, this is not a major problem but to be safe, we recommend placing it in a location far from other corals initially.
