My biggest bn Tim is not very well.
He appears to have a white swelling at the base of his tail, and this appears to be
affecting it, as hes holding the tail fin tightly closed. He appeared restless for the
Past few days, swimming about as opposed to scooting about the bottom and
Sides. He would also have moments of thrashing about in one spot. I noticed the swelling
on Thursday, and affected his swimming, he turned upside -down and waggled about like
That. He appeared drunk, unable to sucker onto things, he appeared to hold his mouth in.
Today, his swimming and suckering are normal, but still has the tail lump.
He is also pale and rather stationary, but that may be due to the hospital tank and slightly over kill filter.
He was treated with fungi and finrot medication on thursday, and was been given revitalizing tonic on friday.
Water levels are normal, and both hospital and main tanks are well oxygenated.

Today (saturday), he has darkened up again, and appears to be behaving normally.

Any ideas? My LFS said it could be a tumour

Does no one have any ideas at all? Even if it's a wild guess, or something I needed worry about at all?
My main thing is if it's something infectious or not, as I would like to move him back into the main tank soon.

looks like some sort of fungal although hard to tell with those pics.
i would treat him back in the main tank anyway if its fungal use a broad spectrum med myxazin or acraflavin should sort it

Heres some clearer pics I just took:
Not sure where that red spot has come from, it's definatly not there on him.

He was less than impressed at being on his back.

Dabbed his tail with some kitchen roll to removed the shiney water.
He's definatly full of beans today, yesterday he just sorta lat on his back not moving for the photos, today he wiggled his fins, flipped about and allsorts Once again it's only on 1 side.

I've been treating for fungal infection with KingBritish, but I think I'll take your advice and get some myxazin or soemthing (my wallet crys).
It does look like it's under the skin, so infection of somesort seems plausable :/

If he is behaving normal again then fingers crossed the treatment may be working.....

As long as it does'nt get any worse then i wouldnt worry to much for now...

but i agree with deano its more than likely an internal infection so what you have been doing already is the best you can do...

i hope he stays in good condition...

Sorry to hear Tim is unwell, Hope he recovers fast, I couldn't tell you what it was. Looks nasty, there is no tank mates that could have given him a nip..??
Sounds like you have it under control tho, best of luck with him..

glad to hear he is one the mend. Looks like it was prob a cut or wood that got infected with fungus or something else. The treatments seem to hav worked. great having the hospital tank handy isnt it. I would maybe give him one more dose of the meds then leave him in the hospital for a week to see how he goes, then back into the main tank which i would treat with broad spectrum anti fungal and bacterial meds...something like melafix and pimafix would be purfect. they are too weak to kill of an infecton but will generally prevent others from becoming infected.
