Common names: Hammer coral, anchor coral
Difficulty Level: Euphyllia is generally tolerant, but must have stable alkalinity to survive.
Feeding: Poor feeding response, so must usually be fed with pumps off. Most common foods are small suspension matter including phyto and roti.
Lighting (Level 5 to 7): Most prefer moderate lighting, but will adapt to varying conditions.
Water flow: Hammer requires medium to lower flow to insure fleshy polyps are not damaged on rocks or skeleton.
Placement: All of the corals in the euphyllia group can be quite aggressive. Torch is the most aggressive and should not be placed near other members of the family. Hammer and frogspawn will tolerate each other in close proximity.
General: These corals all come in either a wall form or branching form. The branching types may be easily fragged by breaking heads off at the base of the branch.
