So far havent had an issue they all get along great they only get crazy when it comes to feeding time splashed water halfway across the living room haha they get a little aggressive towards eachother only never attacked any of my other tankmates
The Single Tin will go in his own Tank The Pacus will eventually be found a more suitable home since these were rescues... so the O's and Jack along with the 3 Cats in the tank and pleco will be left
