I currently have a red tail, and a hybrid (rtc/tsn). I would like to have a tsn as well in the pond with them. I know I have to grow it out to at least 20-24 inches before I put it in with the big guys. But will it work? They're the only fish in the pond. The two in there now are about 24 and 28 inches, and we haven't had any issue. Just wanting other opinions or personal experience with this. Picture for tax lol.
