Yeah probably not the best call but once they got to big for the tank and started being aggressive it was either throw them back in the creek they came from or out on the hot pavement. They were healthy fish they never came into contact with any non native or even non locally caught fish that hadn’t come from the same body of water.Never release captive fish into the wild! Except into private ponds not connected to other water bodies, we have a whole thread devoted to this.
