Hi im not sure if my rtc has got a disease or what it could be but he has like almost like a cut or a hole right behind his gills. I know he has gill curl and i been trying to cure it but i wanted to know if he has somso please bear with me. If anyone can help me identify or tell me of any opinions or even how to cure gill curl. I think my 7 inch RTC looks like he has pretty advanced gill curl on one side. Thank you i appreciate it.
