100 gallon at least. They can't even turn around in that tank and they are still not full grown dude.

The "expert" fish guy was either an idiot or a lying SOB. A 55g is barely an adequate short-term container for one 12-inch Pacu. For two of them babies, you're looking at something in the 150g + range or more. Eventually, you'll need over 200g or more.jlandrum said:They are about 12 inches long. I bought them from a "expert fish guy" who told me they would do fine in a 55 gal. tank. They grew up in the same tank together and do not fight, although when startled they tend to wig out a bit.
