Okay, so I have posted here before about my guy's issues with his tail, and it just seems to be getting worse.
This was him the first day I brought him home:
This was him a couple of weeks after coming home (when I first made a post):
Immediately after that post, I removed all the in his tank and replaced them with terra cora pots and natural plants. But he kept on tearing constantly, he'd get big tears in his fins all the time, so as soon as it would start to heal he'd tear again.
So since then, it has been a couple of months, and the state of his tail continued to fray like that. But in the last month or so, it's started looking like this (ignore the tear in his dorsal fin, that happened a couple of days ago when he got too worked up and seems to be healing well):
Just note that there are small pieces that occasionally fall off, and there are usually little red bits on the tips. Also note that the damage seems to only be on the top of his tail, and that the bottom portion is long and healthy looking (which made me think maybe tail biting?) Also note that the pale colouring in the last picture was just due to lighting. His colours look a lot brighter than when I bought him, like in the third picture.
My first assumption was that it was fin rot, because he has had it once before on his bottom fin, and it looked the same. The LFS told me to use melafix and pima fix, which completely solved that issue right away, and now all his fins (with the exception of his tail) are far longer and fuller than ever. So I tried to do the same this time and it made absolutely no difference whatsoever.
I've got him in a 5 gallon with a small whisper filter on the lowest possible setting, so there is hardly any current. The temperature sticks pretty close to 80 all the time, and the water parameters have been good as I've been testing the water frequently and keeping up with water changes. I've been adding aquarium salt for a few days to see if that would help, but it hasn't helped at all either. There are still pieces of his tail falling off.
Behaviour wise, he's the same as ever. Very active, always gets excited when its food time, sleeps in his plant, the usual.
So I'm kind of at a loss. Does it look like fin rot, or maybe tail biting? If so, what can I do at this point?
