Fish Crazy
Sometimes being lost to start with is a good thing. With puffers, if you had 7 in a 10gal. they would start a "pecking order" right from the get go because they will be in close contact with each other. If you started them off in a 55gal. with just them in it, they could establish their own territory with out too much interaction between fish. When they reach adult hood, it would be more of a "natural" environment and may even succeed in having you own "little" puffers running around.
