Since dwarf puffers are freshwater. I was thinkin of gettin like 4-5 of them(3 females oer male i knw). And mayb a pictus catfish or somethin. They will go in my 30 gallon. Wht mayb another good tankmate like cordoya or a gourmai. Somethin cool to make the tank look nice. I will probly plant the tank too. with tons of hiding spots.
