I think it definately is laying eggs, I only have one other snail - astrea, and I just caught another one doing the same thing on the front glass. Thanks alot!

I had seen my stomatella snails breeding about a month ago, both puffing cloudy mixtures into the water at the same time, I assume that they were breeding...
But now I am pretty sure I can see little babies with their little half shells out and about. I also have lots of little tiny white guys in there, not sure what type they are yet...
They are so cute when they're tiny!
