Glowlight gasping

Hi
I've recently added some glowlights to my 6gal tank. They spent about 2 wks in QT with 7 days of melafix and pimafix.
One of them had a patch on his side that looked greyish whitish. After the quarantine, patch looked a bit better, but not gone completely. Fish behaviour was quite normal, damaged one acted no different from the rest. They went into my main tank a week ago, but as of last night he doesn't look so good. Patch has gotten a bit worse, but more importantly his behaviour has changed last night. Now he seems to be gasping, holding his gills open more than the others, and sometimes hangs out on his own, not too interested in food.
I'm concerned that he may infect the others, not sure what it might be, and am thinking of putting him back in the QT. That may be too stressful though?
Water parms are all ok, other glowlights seem ok.
Could this be velvet? What should I treat him with for that? Not sure what's the best course of action. Any thoughts are appreciated, thanks.

It sounds like a baterial infection from a wounds if it is isolated in one area of the fish. I would definately quarantine it right away to prevent any possible cross contamination. Velvet is more of a braod parasite that shows up as almost a film on the fish of little white spots.

I would never recomment taking a fish that has been quarantine out of quarantine before it is completely healed. Treating the fish now may or may not save it now but will keep the other fish from picking at it if the fish gets lythergic or the others get agressive toward it because it is weak.

:( Sadly the poor wee guy didn't make it.
You're probably right about the diagnosis, and I shouldn't have taken him out of quarantine. The thing was, I had done a week of meds, and for the last few days after that the mark on his side showed no further improvement. It was so small, I figured maybe it's just a scar and will never clear up completely.
Others are doing well, I'm keeping a close eye on them, relieved that it's not velvet.
Thanks.

I just realized it may not be bacterial infection. Gill flukes themselves are possible suspects. The way you described that its gills are hanging open makes me think it's the flukes that are possibly the culprits.

Sorry to hear that.
