+1i would also say none...........just because the fact, you never know the "personality" of any fish, and the reputation that puffers carry with them...........You could get lucky with any type of puffer and find out its a pussycat, but considering most will terrorize the other fish, i wouldnt chance the fins and lives of my other fish........If you want one, a species only tank would be best
Answer I was searching for before I answered with this as well. Good research my friend!Wrong...no offense =P Amazon Puffers do very well in community tanks and actually are so peaceful that you have to watch out for aggressiveness from OTHER tank mates to the puffer. They are that peaceful.
All other species, freshwater and brackish, are aggressive.
