snail identification

[karbomb]

alright i found the source of all the white spots in my tank. they are snail eggs. there are these two snails i got from aquaticplantdepot.com, when i ordered them they claimed they were blue mystery snails, they definitely are not.
so if you could help me identify this bugger, i'd appreciate it.

Looks like a black mystery snail to me. Doesn't resemble the blue ones. Genius is Pomacea bridgesi. But I could be wrong. Just looks like it.

i know it isn't a mystery snail cos of the eggs they lay. i will post a pic of the eggs.

these are the eggs that the snails lay.
and another shot of the snails, if you look below the less in focus snail you can see a white spot.

Olive nerites, the eggs won't usually hatch in fresh water. Some folks claim they will if the pH and hardness are high enough, but the larval stage is nearly impossible to keep alive in an aquarium. They also tend to wander out of the tank if it isn't tightly covered.

wow thanks!
will the eggs go away?

you know i just googled them and i am not sure if they are that type of snail. they are definitely about penny size and they didn't eat any of the green algae in my tank :(

Ya those are not (definatly NOT) mystery snails, or any type of apple snail i have ever seen.

If you could get a better pic of the shell, sideways i might be able to tell you more. I sure hope those eggs dont hatch till you know what it is! But most snail eggs take a couple of weeks to hatch, and to make them take longer you may want to turn your heater down a bit if you can, the lower the temp the longer it will take to hatch.

i am pretty positive they are Olive nerites. the eggs have been in my 10g for about a month now and none have hatched.
if you look in the member gallerys at mine and then under 3g there are some more pics of them.

Cool, well i found this on them and it explains why none have hatched, incase you havent come across it yet :)

"Olive Nerites are relatively small snails, reaching a maximum size of about 1" in diameter. They grow slowly and reproduce slowly as well. Unlike many of the more commonly available aquarium snails that are hermaphrodites, Olive Nerites have separate sexes. Eggs are fertilized internally, and the female lays individual whitish-colored eggs bundles as she grazes along. Although fish seem uninterested in the egg bundles, the adult snails eat the majority of them. A few do hatch into the plankton larval stage, but there are not enough plankton nutrients in out relatively clean aquaria for them to survive to settlement. I have had a few develop into small snails in a greenwater/infusoria tank and outdoors in tubs during the summer months. The small snails grow very slowly. Apparently hard water is beneficial for successful reproduction, since in soft water infusoria tanks, eggs appear but I have not seen any young snails, although the adults seem to adapt fairly well is slowly acclimated to softer water. Like most snails, the young require calcium for their shells to grow properly."
