Arapaima are carnivorous fish, with a diet primarily consisting of other fish. They are opportunistic predators and will also consume crustaceans, mollusks, insects, and even small mammals, birds, and fruits found near the water's surface. In their early stages, arapaima fry primarily feed on plankton before transitioning to insects. #arapaima #fishpond #aquariumhobby #aquarium | Hendrix backyard TV
