Some people say 29 gallons for one piranha, and some say 20 gallons for one piranha. You can keep three but your aquarium will be overstocked, get good filtration and do water changes weekly and you'll be fine.
How do you think a fish of potentially reaching 12" is ok in a 20 gallon? Also Piranhas can grow much bigger than ur acclaimed 13" . 3 in a 55 gallon for life is just ridiculous.
Do you think it would be severely overstocked or doable? I already planned on doing weekly water changes and will have two filters running. The tanks footprint is 48x12. Will that give adequate room for the RBP to turn around? This is what is holding me back from getting them until I know for sure they can fit and not have to upgrade. Online I see many 55g tanks with 3 RBP in them but I don't know if that is just a temporary tank
We'll man I'm not arguing with you but let me just prove my point that I'm right.How do you think a fish of potentially reaching 12" is ok in a 20 gallon? Also Piranhas can grow much bigger than ur acclaimed 13" . 3 in a 55 gallon for life is just ridiculous.
