Well, got home from a 1 week vacation Saturday. Looking closely at the tank Sunday night, I think I see something move in a far, rear corner of the tank, under some pleco cave condos. So I get my flashlight and my cheater (reading) glasses, and lo and behold, 4 or 5 little ones, about 1/2" long each. Can you guess what they are ? I have my suspicions, but I'll see what you think ! And apologies for the picture quality; I had to hold the flashlight just right and snap the pic !!
