The Blackcap Basslet, Gramma melacara, features a vivid purple body with a jet black diagonal cap. Like other Basslets they should not be housed with another Basslets to avoid aggression, but can be kept safely and peacefully in a reef tank with other tank mates. They are very hardy making them easy to acclimate and care for.
Corals and larger invertebrates like shrimp are safe from this Basslet, though they will consume very small invertebrates such as amphipods , isopods and copepods. Diet should include a variety of live or frozen mysis shrimp and vitamin enriched brine shrimp as well as chopped meaty foods like clam, krill, shrimp and squid 1-2 times daily.
