Nerite snail breeding.

Hi. I have a male nerite snail in one tank and a female in a different tank which she has overwhelmed with unfertilised eggs. If I move the female into a different tank and the male into the females old tank, the eggs can’t be fertilised when already laid right? I don’t want a bunch of baby snails. XD.

 

They cannot be fertilized in freshwater

Not quite true, nerite eggs can be fertile & hatch in freshwater but the larvae need brackish to survive.
To answer your question Op, no you will not be overrun with nerite snails

So the eggs could be fertilised without the female present but the baby snails won’t survive?

 

You'll have no baby snails in freshwater. I just scrape the eggs off. They can be a pain to get off. If they're on driftwood just leave them

I'm sure zebra nerites are asexual. I could be wrong but even having one you'll get eggs. I have two who I've seen breeding but I'm sure I read somewhere they can be asexual and fertilise their own eggs

The male is a zebra but he has never laid eggs in the year n half I’ve had him (so I assumed he was male) where as the female is spotted black with orange base.
But thanks for the advice. I’ll go scrape off the eggs just in case when I switch em. Didn’t occur to me to do that at all.

 

I could be wrong. I'm no expert but I read they're asexual. As I said I could be totally wrong. I also thought it was very difficult to tell the difference between male and female

The eggs are difficult to scrape off. You either need decent fingernails or I use the handle of my algae scraper. I won't have any eggs for a week or two then one morning their will be about ten. I've seen them on the heater and filter!

 

Sorry they're not asexual. The female produces eggs for the male to fertilise. So regardless if you have a female your getting eggs. Dont worry about baby snails tho!

 

I've had Nerite snails for several years in freshwater - they lay eggs all over the driftwood & rocks. My plecos eat them. They cannot breed in freshwater. They need to be bred in brackish water with low to zero nitrates.
