Pseudomugil-weird clear spot


Just noticed one of my pseudomugil has a clear spot on both sides and won’t eat. Any idea what this could be? Pics attached

That is a serious bacterial infection. What you're seeing is where the "meat" of the fish has been eaten away.

The first thing I would do would be to test the water and make sure that its no the result of anything environmental -- low pH, high nitrate, nitrite, or ammonia, as well as just lots of organic gunk in the water. Keep an eye on everyone else, and make sure that it was isolated.
