Euphyllia Corals

Euphyllia is a coral Genus name that includes those corals commonly known as Torch, Frogspawn, and Hammer corals. All are common LPS corals that exhibit large, fleshy tentacle heads over skeletons that are normally either branching or wall pattern. They are most easily distinguished from one another by the shape of the tentacles, although some specimens may show mixed characteristics that make an absolute ID tricky.

Euphyllia corals are easy to moderately easy to care for and make a great first LPS coral for most new hobbyists. Aggressiveness is high for all Euphyllia because they are prone to produce sweeper tentacle formation and will aggressively sting any near neighbors that they brush against.

Lighting should be moderate as well as water flow. These corals have a sharp skeleton at the base of the polyp and excessive flow can cause tearing. They may also fail to fully expand under high flow conditions. Euphyllia prefers to be placed near the middle of the tank since intense light may cause bleaching. They are somewhat forgiving of temporary nutrient level lapses. Maintain proper Calcium, Alkalinity, and Magnesium levels for skeletal growth.

Special Notes
Take care to allow the Euphyllia to fully close before moving them to avoid tearing. These corals are prone to bacterial infections often called "brown jelly infections" if stressed or damaged. Infected heads should be removed immediately to prevent the spread of the infection.
