The Lantern Basslets are perfect for a starter fish!They need atleast a 10 gallon saltwater aquarium with plenty of live rock for hiding. Typically not considered agressive, they can get aggressive towards other smaller fish. They will tank mate with same species but should be added at the same time. They are considered reef safe and will not pick at corals or sessile invertebrates, and are a great fish for the reef aquarium that does not contain small fish or shrimp. The Lantern Basslet requires a diet consisting of a variety of chopped meaty items, frozen brine and mysis shrimp and sometimes will eat flake foods.
