My Friend's Fish is Dying

[vanillaxtiffy]

Here's the video of her fish's lesion http://www.youtube.com/watch?v=sjxW9dvqH_A [for anyone who doesn't click links, her fish is basically disintegrating from the outside in. It's fins started melting away, so she thought it was finrot, but then all the skin came away too until you can see to the bone]

She made that the other day, apparently now these are appearing all over his body and he's not moving much, if at all. Does anyone have any idea what this is and how to fix it?

[The fish is a "mudpie" I don't know what type of fish this is, because when I googled it all I got were recipes for mud pies...]

Looks like a catfish to me. What size tank is it in?

I'd do a water changes for the next 7-8 days in a row, add a half dose of salt and half dose of Melafix and Pimafix It has done wonders for me

Yeah, it's a catfish. I just don't know what kind. She has it in an 80g. I think we've got it solved, I was thinking it might be columnaris so I asked if it had any cottony growths and she said it has them all over (remember, that video was when there was just one lesion, now the poor fish has many more) so we're thinking it probably is columnaris and another friend asked her biologist friend who confirmed. Thank you for the help though!

If the lesions appear to be bloody like the video, that is not typical of Flexibacter columnaris to me. The disintegration of fins however does indicate bacterial infection is one of the problems. Is it only by itself in the 80g? If not, isolate the fish since any tankmates will nibble the wounds and worsen them until the secondary infections could potentially kill it. What are you treating it currently? At the moment, any bloody lesions can be treated with mercurochrome swabbed on a cotton to avoid further infections.
