I thinks he’s been doing better he’s now not swimming into things and he’s just chillin my the plant. Still breathing heaviler then anyone else

These shots say a lot to me. This fish is pretty messed up. The head and the cranial shield are mangled up, uneven, badly asymmetric. The eyes are sitting asymmetric. The snout is asymmetric. Left gill plate is missing a piece. The pectoral fins are messed up. The dorsal fin is not quite centered on the body. The backbone is curved in the side shot.
I don't expect this fish to be viable because there is no reason the mess is only visible on the outside and every reason to expect the internal organs to be messed up too. Heavy(ier) breathing may point to it too. Chances are it will perish sooner than later.
So all in all, there is some truth to your statement that only this RTC concerns you. But your tests do show problems with an incomplete nitrogen cycle. And this is crucially important to understand and address. Losing a plat RTC is nothing compared to this issue in your long term fish keeping hobby.
