Hi all, I have noticed my Betta seems to hve a black line edging his tail fin (caudal?) and then i noticed a 3mm slit in his tail, like a hole halfway in. So I thought that maybe he has fin rot, so applied the treatment to the tank. This morning the slit had lengthened and come right through the tail, making it look like a ct slit tail. I happened to mention it in my lfs, as there was a betta there identical to my Blaze, and she said not to worry, as th dragons sometimes turn into Crown tails....is this right?his dorsal fin has ct edging, as does his pelvic fin. So I can see how a ct conversion could occur, but seriously is this a possiblity. I would rather know as if he's not ill, I need to stop the treatment, thanks
