Lyretail Anthias White belly?

Someone help me figure out what’s going on with this guy? He’s by himself and not doing too great. He’s the only one out of three others that seem to have this issue.

He looks thin. I would almost say uronema - but the video is not that clear - could also be bulled - can you give any more information

The kids say he might be picked on by the others … I’m not so sure, I think there’s some better shots later in the vid

Looking at the shape and location, it is indeed uronema which is an oval ciliated motile protozoan which causes tissue necrosis as seen on fish. What other fish are in the tank?
This can also be triggered by low salinity levels as well as excess food waste on tank bottom which this protozoan can feed on as often prevention can be more valuable than cure for this.
Fish will have to be quarantined and treated with formalin based treatment which is harder to find, so next option is Ruby rally Pro. Chloroquine Phosphate will also work but must be used precisely. Uronema is not an obligate parasite, and can thrive on bacteria, uneaten food, and waste so besides treatment also maintain a clean tank removing waste daily.

I agree, could very well be Uronema.
