Gramma melacara
A Caribbean basslet with a purple body and black cap. Lives alone on deep walls and often hangs upside down in caves. Hardy, suitable for small tanks and reef safe.
The blackcap basslet (Gramma melacara) is a small member of the family Grammatidae from the western central Atlantic, in the West Indies including the Bahamas and along the Caribbean coast of Central America. It lives alone on near-vertical cliffs and drop-offs beyond the outer reef, usually at 20-60 m and most commonly deeper than 30 m; the related royal gramma dominates in shallower water and is gradually replaced by this species at 15-30 m. It hovers upside down beneath ledges and darts into holes when alarmed. The body is vivid purple with a black diagonal band from the top of the head to the front of the dorsal fin. Maximum length is about 10 cm. It is easy to keep and can live in a small tank if given rock caves for shelter; as a deep-water fish it prefers subdued lighting. It readily takes meaty foods such as frozen mysis and chopped crustaceans. Once established it becomes territorial and fights with other basslets, so do not mix them. Apart from tiny crustaceans it is harmless to corals and invertebrates and suits reef tanks. It has been reared in captivity.
