I was watching the two for about a half hour after I added them to my tank. I watched them for a good 15 minutes at the LFS and hadn't noticed what I did now. It looked like one of them had a zit under its jaw. His underside is white (and it should be) and this round, pimple-like bump blends in. Should I be concerned with this? What could it be? What should I do?
These are Harold Schultzi cories - mainly peppered body, clear fins with some black spots in them.
