Bullseye Puffer (Sphoeroides annulatus)


A freshwater to marine puffer found along the Pacific Coast of South and Central America, the Bullseye Puffer is a large growing and attractively marked species. When young, they are often found in pure freshwater but migrate to brackish or full marine waters as they reach adulthood. Like most puffers, they are prone to nipping the fins of other fish, so should be kept with hardy, fast-moving tankmates (if any). This species can be kept in  groups, although they should be fed heavily and given plenty of cover to avoid aggression.
