Yep, from all i've heard catfish, heal breaks very fast, and i've expirienced this my self. My Syno cats sometimes get a bad Bruce, and the NeXT day its almost healed up. If it dosnt, i'd start researching the use of salt. (Some cats are sensetive to salt, dont know about the RTC x TSN Hybrids) Good luck with him, as i said earlier, he has a very nice pattern. (Even tho, you dont want tips on tank size, wich i understand, my best tip is to start looking at an indoor pond, or outdoor depending where you live)
