White patches on odessa barb

[courtneylm]

My odessa barb has 3 white patches on him. I noticed the first one about a day or so after I put him back in my main tank. He had been in quarantine for over a month because I thought he was injured, then he stopped eating, and just when I was about to give up on him he started eating again. Then my main tank had a leak, so I pulled all the fish and everything out to reseal the tank. Once the tank had cured and been leak tested, we set the tank back up and put him back in with the other fish. Again, a day or so later i noticed the first white spot, and a few days later I noticed more. He seems to be fine otherwise. The parameters in the tank are pH 6.6-6.8, ammonia and nitrites 0, nitrates 10, temp is 78. I haven't noticed this on any of the other fish. Before the leak the tank had been set up for 4 1/2 months, and we refilled on 4/4. TIA!

Do the white patches look fuzzy/fluffy?

Is that the only fish with it? To me it looks like possibly a fungal issue so I'd treat with a anti fungal medication and lots of water changes to promote healing

If the white patches are a little fuzzy, then possibly abrasions w/ fungus attached. Usually harmless & will heal up on its own.
Smooth white patches often indicate a bacteral infection. Not a good situation & difficult to cure.

They don't appear to be fluffy. None of the other fish currently have any that I've noticed, however a little while ago I noticed one on one of the rainbowfishbut it cleared up on its own. It happened after I did big maintenance on the tank, I thought it could be stress related when it happened to him. I thought that could be the case this time as well since he had been out of the main tank for so long, but he got a couple more which is why I got concerned.
The patches look kind of clear, and they seem pretty flat against his body

Just to update, the spots have cleared up. I did not medicate, just kept an eye on him.
