White spot

[watchdr]

I posted this in the fish disease forum and no one seems to go to that forum.

So here is my problem I am hoping someone on this one can help or has some ideas.

White patch that won't go away!
I bought two neon blue star damsels from a LFS. This was about 7 weeks ago.

Put them both in a QT. The next day one of them had a white spot about the size of a scale on it's side. It looks very slightly raised and has not spread on him or the other fish.

They both eat great and everything else about them look fine. I have never run into this before.

I have treated for fungus, parasites and baterial infections. I treated for the bacterial first then fungus thinking it was more than likely those. Treating for parasites is only because the others didn't work and I am grasping at straws trying to figure this out.

Nothing has affected this white spot. Could it just be a scale is coming loose and just hanging there? Or is it some other disease that I have not found the cure for yet? He does not scratch himself on anything trying to get it off.

Any help would be great. I can't get a picture of it because he is either hiding or to fast for the camera!

Hard to say w/out a pic, but the trouble you're having now is probably nothing compared to the trouble you'll most likely have trying to catch those damsels after they've thrashed a few of your favorite fish!
Rarely do I see someone who is able to keep damsels in their tank w/out them becoming aggressive.

It could be a scrape or wound from eithe rubbing against something or from the other fish picking on it. Post a pic if you can and we can try to make a better assessment.
