I agree, very time I buy more then one rmthey fight each other but leave the tankmates alone. but I seem some Almost fully grown where they are together. I wonder how that works. I know this guy who sells them and he says he keeps them by themselves until they reach a 12” then puts them in a tank together.Not surprising at all. Almost all groups of them end with 1 survivor. They will tear at each other's eyes and bodies. I've tried as well as many others to end in just 1 fish left. Even massive tanks have the same issue. 1 fish is best per tank!!!
