None of those fish will be safe with your RTC in a few months. If it can fit it in his mouth he WILL eat it. Even if half the fish is sticking out of his mouth. He will grow at least an inch a month. It's good you have that pond. I would start thinking about what you want to add to that pond NOW! Clown Knife, Gar, Pacu, Arapaima, Peacock bass can all work....but they must be BIG NOW!!! or he will eat them too. How deep is your pond?
