I have a 20” redtail in another tank, they’re BEASTS. Definitely not looking to get another one of them lol. Thing eats everything even my filter propellers. But basically your saying that pbass will make good tankmates even once the aro and the bass are fully grown? I have a pleco in with the aro now but I hate that bastard he’s a fish eating crazy pleco. He’s going to be moved soon
