I am cycling my 75 gallon right now. It has a 20 gallon sump turning over around 5 times per hour or so (will increase as I improve my design). My girlfriend really wants a puffer but it will be me taking care of the fish. My question is what would be the best puffer or puffers for this tank. I am ok with fresh or brackish and will convert to full marine if I really have to. But I want a really fun fish. Something with all the personality everyone always talks about. Being able to keep a couple tankmates would be nice too but not necessary.
