I know this should be in the invert section, but I have already posted there and got no response. I was hoping maybe someone with brackish experience might be able to help me. I have a couple of zebra nerites in my brackish tank. I woke up this weekend to find the tank covered in snail eggs. I was wondering if anyone knows how long the eggs take to hatch, or how to tell if they are viable. Any sites that you know of that actually talk about these snail's breeding habits. Everything I find just says that they only breed in brackish, but no more.
Nerite eggs

Well, since no one seems to know about this I'll keep you posted if anything develops with these eggs.
I have read about a theory on Neritina reproduction. It states that the eggs are laid in either fresh or salt water. When the eggs hatch, the larvae is pelagic and is carried to higher salinity along the river estuary, where it developes into adult.
Taken the fact that an adult snail must then migrate back to lower salinity to reproduce, it sounds a bit hard to swallow. But it might be true.
I have had thousands of Neritina eggs in my brackish paludarium, but I've never seen a baby Neritina snail in there.
Must try and remove some eggs the next time I see any laid on a suitable, removable decoration. And see what happens if salinity is raised for them?

Well, I don't think anything is going to hatch. Now I just get to scrape these eggs off of everything that's covered with them.
