I'm kind of new to this. My 20 gallon just got done cycling a few weeks ago and I decided to add my cories. I didn't have a quarantine tank with aged water, I would have had to start with new water and no seeded filter. Now I'm regretting it.

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.

Ammonia: 0
Nitrites: 0
Nitrates: 10ppm
PH: 7.8 (same as LFS)

Thanks
