They are very round and have a chunk of what appears to be mud or feces attached to them. I removed one and smashed it, the black chunk and it was a really thick dry mud like stuff. Almost like charcoal. And the egg was soft and juicy and had nothing in it but a jelly like stuff. I hope they are snail eggs and not some weird aquarium bug! I have Nerites and assasin snails in the tank.

Thanks!! Cory eggs!! Awesome!! They were swimming crazy this morning all over the upper levels of the tank. They may have been eating some of the eggs. The black stuff is only on some of the eggs, and it looks like it is hanging off the eggs and attached to the eggs. The black stuff appears to be on the eggs that are up in the plants, and one is on an egg that was laid on the intake screen. It's really weird. It's like mud or dirt. It is not anything that is alive. I thought it was a snail eating an an egg at first. Very perplexing!!
 
I think I know what it is!!! It's gotta be small pieces of the aquariumplants.com substrate that I use, and it got stuck on the eggs when the discus stirred up the substrate eating this morning. They sometimes bolt and really send the substrate flying!! I think that is it!
 
that is probably it. Plus the female holds the eggs cupped under her body in her fins as she swims around hectically placing them. Its possible some debris got stuck to the eggs when she was deciding where to lay them. My cories spawn constantly but usualy eat the majority of their eggs. I have heard that sterbai often have several unfertilized/unsuccessful spawns before they really hit full maturity and you get a good hatch rate. Congrats though, they are wonderful little cories and one of my personal favorites.

Thanks so much for your help! And thanks for sharing in my first cory spawn. For years I've wanted my bristlenose to spawn...and I never even considered that the corys would, because I thought corys were very hard to spawn. Who knew they would be my shining stars! Sterbai are my favs too. These guys are right around one year old. I have 6.
 
alot of times once they start they will keep spawning again and again for awhile. Its really fun to watch if you get a chance. The males and females do a neat "t" formation dance for the eggs to be fertilized and watchign the female carry them around and gently place them in fascinating.
 
It's kind of weird, the Discus spawned last night too. I ran out of CO2 Friday afternoon and haven't got around to replacing it today. Wonder if the change/rise in PH had anything to do with the sudden cory activity.
 
it could, alot of times thunderstorms will set them off or drastic changes in temperature or even larger than normal volume water changes (maybe the drop in TDS).
