Hammer Coral

Its common names are derived from the appearance of its hammer-, or anchor-shaped tentacles. It may be green, tan, or brown in color, with lime green or yellow tips on the ends of its tentacles that glow under actinic lighting. Some varieties may be branched which makes them look similar to a Torch Coral.

It is moderately difficult to maintain, but with proper water conditions in the aquarium, it will thrive.At night, its sweeper tentacles can extend up to six inches in the reef aquarium, stinging other species of corals and animals. Allow plenty of room between it and other neighboring corals. For continued good health, it will also require the addition of calcium, strontium, and other trace elements to the water.
