Remarks. Roberts (1989) commented that B. macracanthus fed mainly on plant detritus; however, Zakaria-Ismail (1992) observed that B. macracanthus could be caught by hook-and-line baited with earthworms. Our observations of captive specimens in aquaria and other aquarium literature (e.g. Finley, 1995) indicates that B. macracanthus prefers to feed on aquatic invertebrates such as chironomid larvae (bloodworms) rather than on plant detritus.
