Large Swelling On My Zebra Danio

[arnold]

Hello all

Over the weekend, my Zebra Danio has began to swell. Im quite concerned about it as it looks quite painful for the little fella, and it keeps getting bigger.

I've worried it's going to pop or die or something

I have 4 other danios and they're absolutly fine. I also have loads of other fish and they're not showing any ill symptoms.

I've inserted an image, hopefully you can see whats what from it. The swelling is red too, although as you can see, its complete undercarriage has got bigger.

Thanks guys!

Sorry there no hope for the fish I would end its suffering, when did you last see it go to the toilet.
Looks like it organs have packed in and causing poisoning of the system septicemia.
