Today I was inspecting my tank and I noticed these weird looking cysts on my cory cat. Just the 1 out of 6. I attatched a pic if any on can tell me what it is. There is the bigger one on the side fin, one behind the dorsal, and one on his tail. It doesn't look like ick to me because the rest of the fish in the tank are fine. he seems to be acting normal other than the growths, but I put him in the q tank by himself just to be sure, Any help is as always appriciated. Thanks
