Lupin gave some good ideas.
As to puffers... most puffers that get over 4" are either marine or Brackish. You can be able to do one, possibly two (as in a pair) of Green Spotted Puffers in there (Brackish). They reach 6", which means you would need to feed more than snails as they like to eat crickets, gut loaded shrimp, worms, snails the size of their eyes, etc. They also gradually reach almost full marine as the age, so that may draw you back.
