None. They get much to big for a 20 gallon tank (around 12 inches) total. I would suggest getting a bigger tank or a smaller fish.

you would be greater suited off to place a single piranha in a 30 gallon. they're very messy eaters and the enormous water volume is there to off set that. in case you keep communities of piranha you could guess in time you will purely have one left . Your greater suited off to maintain a single fish particularly that a team.

They can grow up to a foot, so I suggest you get a bigger tank. You could maaybe try to fit one in there, but he'll be cramped.

none, the tank is too small. You need at least a 50 gal.
