Fish With An Exploding Belly

[LoudSaxo]

I have a 72ltr tank

28degrees

No idea about the levels at this moment - water cycled regularly

All the other fish seem fine (tetras and guppies) but I appear to have a white Molly that looks like its belly is bursting, it's swimming around ok, but looks like something is hanging out of it, not full on guts, but a thin white thing, kind of looks like a dangling fin that's loosely curled up - its quite an old fish and has been fine for some time. It's belly is deffo rounder and looks like its split or damaged his underside to some degree - I feel sorry for it.

Any ideas? I've never heard of this kind of thing.

I can probably get a pic if necessary.

A pic would be good so we can see where it is "coming out" and what it looks like
