Extremely odd!!!!

My Yellow Tailed Blue Damsel has what appears to be an airbubble over one of it's eyes. This bubble has got larger over the last few hours. It doesn't appear to be a swollen eye. Can anyone tell me what this might be?

It sounds like Gas bubble disease.

Are you serious?

I heard putting the fish in QT with epsom salt will relieve the problem. You can google GBD and see what comes up.
