An excellent choice for a reef aquarium, the Black Cap Basslet is a threat to only the smallest invertebrates such as Copepods, Isopods, or Amphipods. Provide at least a 30 gallon tank with rock caves to hide in. Black Cap Basslets can become territorial once established, so they should not be kept with other basslets. Because they tend to be deep-water dwellers, they do better in an aquarium with slightly subdued lighting.
Black Cap Basslets will do well on a diet of meaty foods including marine fish, crustacean flesh, mysis shrimp, and quality frozen preparations.
