An attractive freshwater aquarium oddity, the Spotted Puffer is attractive, active, and amiable (in appearance.) This friendly-appearing fish should be kept only with semi-aggressive or aggressive fish. It may likely nip the fins or slower moving or more timid aquarium mates. Considered a brackish water fish, this fish does fine in freshwater as a juvenile, but should be kept in brackish water for longevity of health. As with other Puffers, it should not be kept with smaller snails, crustaceans, and mollusks, as these compose a large portion of its natural diet. Bloodworms and blackworms (in addition to a high quality pellet food) will help sate the appetite of this eager eater. Hard, alkaline water in the 76-82 F range is ideal. It is very common for these fish to nip the tails of its tank mates. The tails do recover with some time as long as the nipping does not continue into the future. A large aquarium is helpful in preventing this behavior.
