Need Help....quick!

[clairebear76]

Hi guys
I've got up today and one of my Danios is swimming around at the top of the tank with its rear end almost poking out of the surface, its not righted itself at all and looks like its having trouble swimming. Its also got a very thin white "growth" (maybe a worm type parasite) coming from the bottom edge of its mouth. Anyone know what this is so I can get down to the LFS and get some treatment?

Thanks, will do. If it's any help the faint dark markings they've got over their eyes and in the middle of the top of their heads has gone really, and I mean really, dark!

The worms does it have a forked tail.
Can you describe the worm in more detail, the colour of the worm.
Or is it strands of cotton coming out of the mouth,.
