Comet with red, 'threaded' fins

Hi folks, I was wondering if anyone on the group could help me work out
whats happened to my comet.

Hes about 8 years old and is about 12 - 13cm long. He's currently in a 13
gallon tank (bit small I know, but finances don't permit an upgrade ATM).

I noticed this morning that he was lurking at the bottom of the tank behind
ornaments etc, and upon further examination I found that his fins and tail
were a very dark red, and had 'string' like things hanging off the end of
them. In fact, a significant length of the end of his tail was missing
completely.
I investigated further, and found that these 'strings' were in fact the
veins of the fin (don't know their scientific name sorry), it appears that
the 'webbing' of the fins have been eaten away by something, leaving just
these veins trailing.
The severe redness of the fins and tail leads me to believe it has been
burned in some way... possibly by the water PH or similar.

What I wanted to ask was, is my analysis of the problem accurate, or is
there a disease which can cause the above ?

There were 3 other fish in the tank, a black moor and 2 fantails, all
relatively tiny. These were removed 5 days ago because the black moor was
constantly bullying the comet and attacking his tail.
The thing is, he did not have this damage when the other fish were moved
away, so I don't think that was the cause.

He is currently in a bucket and I have drained the tank completely to wash
out the gravel and filter...(I found a piece of the missing tail end while
I was doing this :-\ )
I guess my question now is whats the probable cause of this, and what can I
do to try and ensure his survival / recovery ?
He is still swimming and feeding, which is a good sign at least.

Any help or advice would be greatly appreciated,

Thanks.

It sounds like your comet has severe finrot which is generally caused by
poor water quality. You need to buy a water testing kit (most important are
ammonia, Nitrites and nitrates) and make sure your water quality is up to
scratch. After a tank has cycled you shouldn't have any ammonia, no
nitrites, and less than 20ppm of nitrates.
You need to buy some medication to help stop the rot and encourage new
growth. Melafix is excellent and so too is Interpet number 8 fungus and
finrot treatment. I'd get it a.s.a.p and follow the instructions carefully.
Make sure you follow the whole course. He should then make a full recovery.

if you recently put the other fish into the tank, they could have brought disease
into the tank with them if they werent quarantined for a month.
that is also small tank for 4 fish and they could have tipped the water into toxic
conditions.
do a peroxide dip on the fish.

follow exactly. then keep changing some of the water every day. add 1 teaspoon salt
per 5 gallons. Ingrid
