Hammer Coral grows with a variety of colored tentacles atop a bony hard coral structure in the Large Polyp Stony (LPS) coral category. Hammer Coral is highly sought after by beginner and experienced hobbyist alike. The Neon Yellow Hammer Coral is a relatively new hammer color variation.

As part of the Euphyllia family, Hammer Coral is known to send out sweeper tentacles several inches further at night than commonly seen during the day and can sting nearby corals. Care should be considered in placing this coral several inches from corals outside the Euphylia family.

Hammer Coral will require moderate lighting combined with moderate water movement in a reef aquarium. It gains much of its nutritional needs from proper lighting and it thrives on supplemental feedings of meaty foods such as Mysis shrimp or micro-plankton.
