Strange critters on glass.

Woke up this morning to find these strange things on the front glass. They're like little suction cups 1/8" diameter stuck to the glass and they don't seem to be moving. There are three groups of three in different locations, all laid out in almost exactly the same orientation as in the pic. They feel like hard rubber. Any idea what they are?

Hey, am I correct to guess these are cory eggs? I have some peppered cats and a quick google shows they look similar.

Edit: Just found a larger group of them on back glass. How long does it take to know if they are fertile?

Do you keep Nerite snails in your tank as well?

Wasserpest, not that I know of, but now you've got me thinking.

I just did a search about nerites as I'm not familiar with them. The only pictures of their eggs I found are too hard to id properly. Do you know of some good photos and information?

I collected some eel grass from the wild a while ago and although quarantined them, maybe some nerites got through?

Hmmm, I don't think I'd describe them as sesame seeds like nerite eggs are compared to. They definately look more like these cory eggs, except they are pretty much clear. Also, I just found the majority are on the glass surrounding the canister instake. Isn't that typical for corys to lay the eggs near good water movement?

1/8" is too large to be nerite eggs which are 1mm across or 1/32".

Yeah I'm pretty sure now they're cory eggs. One of them is pretty fat. Is it usual for them to get a pinkish color underneath when in berry (if that's the correct term?) Also it seems they may be infertile. I read somewhere the eggs should be an off-yellow color rather than completely white if fertilized. Is that correct? Then again another page said to just wait since weird things can happen. I'm not really keen on moving the eggs as I don't have another tank set up at the moment, but the adults aren't eating them yet. I guess if they hatch they'll end up in the canister since they're so close to the intake. Makes me feel bad. But at the moment I've got mollies, apple snails, ramhorns and MTS's breeding like crazy. Somehow my tank inhabitant's have seemed to get hold of some viagra behind my back.
