Powder browin in trouble

[davechee]

Hi All,

Wonder if you could give me some advice.

My powder brown has a swollen stomach and it's fins are torn. It's mouth is open all the time and it can't swim properly. It keeps swimming into the rocks and doesn't seem to be able to steer properly. It appeared to be okay when I last checked it this morning, so I was very surprised to see it like that this evening.

Thanks

You can see from the picture that there's this white "ring" on its body marking out the part of it's tummy that's swollen.

Fish died during the night. Thanks anyway.
