What would the salinity level have to be to hatch nerite eggs? Is there away you can tell me without the gravity thing as I don't have a measuring thing. Something like how many teaspoons per gallon or something like that.
Any help would be appreciated! :)

I was wondering if I could perhaps hatch them in a 2 litre container?
 
err, hatching nerites is going to be very very tough. The young hatch into an intertidal zone that switches from full fresh to full salt twice a day.

Man I was so looking forward to having more of the little guys :( How would you even do that? Have to containers and net them in and out?
 
The velligers (larva) require microalgae or phytoplanktons before they develop into snails. That's the challenge to keeping them alive.

Phyto is easy to acquire and feed, just expensive. To me, matching water conditions would be the bigger challenge.

SG needs to be read based on gravity (as in a hydrometer) or the speed of light through the water (as in a refractometer). You can't count on X teaspoons of marine salt in Y gallons equaling the correct parameters.
 
Actually I hear that hatching nerites does not require salt at all. I got 1 nerite snail about 3 months ago. Soon after I got it I notice little white dots all over my aquarium rocks. I recently found that the egg caps were peeled back like a tin can opened 95% of the way. There a tiny specks swimming around in between the rocks. I'm not sure what the tiny specks are bit I am certain that they are living creatures. I don't know what else they could be besides nerite larvae. If they survive long enough to become snails is another thing. I contacted a woman names Wilma to see what she thought they were. I tried to get pictures but they are barely the size of a ink pin dot. her website is www.wilmasthecause.org She has some info posted on the site and says that she has raised nerites in freshwater. I am convinced that my eggs have hatch although my aquarium is not freshwater it is semi brackish. Hope you find the website useful.
 
Those are Olive Nerites. Zebras are different species.
 
Well I suppose I can't delete the 2nd duplicated post. Sorry about that guys! I thought nerites were all the same. hmm guess I just learned something. Thanks Vampie. So if they are a different species then do will their eggs hatch differently and require different environments? From what I understood all Nerite eggs require the same water conditions to hatch a survive. I do find little information on these specific snails. I'm glad someone can correct my missunderstanding.
 
what if you setup 3 tanks.... 1 full salt, 1 full fresh, and 1 brackish with LOTS of flow (powerheads or closed loops)

put them in a net of some sort--- put them in the freshwater, wait a while put them in brackish, wait a while and put them in salt-- and keep alternating this untill they hatch?

But what would it achieve? Why do it like that and not just two tanks with fresh and salt?
