Natural History: This small puffer is the most commonly
available species in the aquarium trade. Though small and slow moving,
these are aggressive fish that will nibble the fins off aquarium mates
and, eventually, kill and eat the other fish.
The four sharp teeth that give this genus its name are capable of
crushing snail shells. Thus, if kept in a large enough aquarium with swift
swimming fishes, puffers can be used to keep snail infestations in check.
Though figure puffers can survive for short periods in fresh water,
they require brackish water to survive.
