Hey I have a fish that seems to be getting a bubble over one of his eye's, I think that the bubble is made up of air, and I don't think it is any kind of tummer but I wana know how to treat it
For now, just do a large water change in your tank, and keep a close eye out for any fish harassment.
Bubbled eye is called popeye. It is normally caused by eye injury or a bacterial infection.
Is your fish alright otherwise?
