Think that might be more of your corydoras eggs. They tend to scatter them everywhere. @NCaquatics can confirm or correct though!

Do you have snails? If so, what type. I agree that it s an egg of some type.

I apologize, I missed your stocking on previous post. I honestly don’t know but curious to what you find out. Anybody else?

 

[UnknownFishies]

My guess is snail eggs.

 

[FishGuest5123]

Nerites aren’t suppose to reproduce in Freshwater.

 

[UnknownFishies]

Yeah, that was really all I could come up with.

They're not eggs. These appear to be a pocket of anaerobic gas.
