No, they just leave eggs that will never hatch and leave white spots all over everything that will never go away.
I don't know why people don't mention this. My mystery snail isn't the best cleaner upper so I got one zebra nerite.
In two days my driftwood was covered with sesame seed nerite eggs. I moved the nerite to the smaller Betta tank, which is now covered in nerite eggs.
I don't know how such a small (relatively) snail can hold such a large volume of eggs. And no personality whatsoever. Moves at a snails pace. (Lol)
My mystery snail zooms around the tank. Slides down this particular piece of driftwood like it's a ski jump and lands on top of the little cave. Devours the food I put in for him. I probably watch that snail play more than I watch the Betta in with it.
Kind of slack in the clean up department though. He will eat the leftovers but if he's eating algae it doesn't show. I wish he would eat all those nerite eggs. I couldn't even scrape them off the driftwood by hand. Those things are eternal, it simply defies the laws of biology, "I won't live, but I won't rot either".
I don't understand why this isn't discussed more often. I can't be the only one.
