I know that supposedly Nerite snails can't breed in fresh water. Though I've read about exceptions.
My question, though, is what exactly do they mean by breeding. Do they mean the eggs won't hatch unless they're in brackish water, or that they actually won't mate with each other unless they're in brackish water? Because I'm pretty sure my two nerites were mating last night. hahaha. They've never been together before- I have a 10 gallon divided 3 ways and one of them is a really bad cleaner while the other is awesome at it and that section is practically spotless. So I was going to swap them, but when I put the good cleaner snail in the other section, I couldn't get the other one off the glass. So I left them both in there and then last night I went in and they were in an... intimate position.

So... were they mating or just sitting on each other in a really awkward way? Will the female lay eggs now? I know some people say their nerites are always laying eggs, but I've had these two for almost 3 weeks and I've never seen eggs in my tank. hmmm.. this is really interesting. Thoughts?
