Cory Catfish- Parasitic infections?

[turtlefish]

I have a few corys in my 10 gallon that has been through some sickness lately. The fish mainly show signs of rubbing themselves against rocks, EXCEPT its ONLY the underside of their mouth, no where else. They eat, swim, and look otherwise perfectly fine. So recently, a few of my corys started doing this too. Again, its only the underside of their mouths, directly underneath the mouth, I guess on what you would call the chin. What parasites do corys get (common ones?). What symptoms would they show?

Hi turtlefish, what type of substrate are you using for the cory cats' tank?

EDIT: Also, what are your water parameters? That tank sounds a bit overstocked, and cories can have problems around their mouthparts due to poor water conditions/waste in the gravel - this is especially true with their barbels. Have they lost any barbels?

 

[turtlefish]

Their barbels are fine. The tank has a triple rrated penguin 150 on it so its ammonia/nitrite are good. I do often water changes to keep nitrates down low. IT was a little overstocked though.

Spot itching like that is almost a clear indication of some sort of parasite. Treating for it with healthy fish should not harm them in any way.

Yes java..good boy. As java pointed out LOL google would have told you that. Just sometimes you have to read between the lines.
