How many inch sized piranhas can live in a 40 gallon tank and for how long?
I was was going to upgrade the tank to 400 gallon tank once they got older but how many inched sized red belly piranhas can live in a 40 gallon tank and for how long
Why not just upgrade to the 400 now instead of upgrading later? Avoid a lot of hassles that way.
