snail eggs?

So I ordered these snails off ebay a few weeks ago just to clean up the algae in my fish only tank and a snack for the wrasse,puffer and trigger and for the price it was worth it. I think they laid eggs? If you know what kinda snails they are I have no idea and if they are eggs how long till they hatch? lol

Looks like a nassarius snail, don't know about the eggs but the timing sounds about right.

 

Def. snail eggs but not sure from what kind of snail? Are the snails you ordered off of ebay the only snails you have in your tank?

 

Yes they are

 

The snails are nassarius snails. They bury themselves under the sand bed and come out when you feed them? If so, nassarius.

As for the eggs, I have had a lot of nassarius snails for years and have never had them lay eggs like that. Congrats if you get baby snails; I have wanted free nassarius snails for awhile!

 

Nassarius snails don't eat algae, just fyi.
