The Twin Spot Basslet , Serranus flaviventris, is a rarely seen Basselet that has recently been captive bred and is now available for the home aquarium. They are best kept singly, as they can be territorial but can be housed with other lager fish. Having plenty of live rock is also suggested as a darker environment is preferred.

Due to their predatory nature, they are not good reef dwellers since they will eat smaller fish and invertebrates  and sometimes tube worms like feather dusters that are present in tank, though they will not eat or bother any corals. Diet should include a variety of live feeder marine fish and feeder shrimp as well as chopped meaty preparations including shrimp, krill, fish, crab and squid, once daily.
