The attractive Hammer Coral Euphyllia fimbriata is a reef keepers favorite large polyp stony (LPS) coral. It is a Euphyllia spp. The Hammer Coral and the Anchor Coral are very similar except the Hammer coral polyps have hammer or “T” shaped tips.
The Anchor corals lack the “T” shape, rather they have semi-circular or sausage shaped tips. Though the Hammer Coral has a straighter and flatter tip, there can be curvature in the tip. There are also very nice branching anchor corals in this genus such as Euphyllia parancora.
