One of my Aenus corydoras has a couple of spots. one on the lower point of his tail fin, and another on the point of the next fin up his body(near the anal area)

the spots appear to be a thickening of that part of the fin, and roughly the size, texture and color of a cory egg even though i know for sure they arent. no pics sorry cant get a good one. i thought perhaps ich at first, but thats the only fish affected, and it doesent bear the appearance of ich that ive heard described to me. any ideas or advice would be nice.
