u can put a baby puffer in but when it grows full size u r going to have to get a larger tank any other fish u want to know about

For a 55 gallon you could always go with a Valentini puffer. The fish are fairly passive, and don't outgrow 4 inches or so. Anything else and you are going to start seeing aggression problems and degraded water quality pretty soon.
