No pics of the shell? It's going to be hard to ID them from those pics

Can't find any other pix from that tank. Those were taken in 2007. I'mm 99% sure I only bought nassarius snails though.

It's certainly a Nassarius Sp. The question is which one? Without a shot of the shell it will really be almost impossible to be sure but if I was to guess I'd say Nassarius distortus. Which BTW is also my guess for the larger species that I have in my tank.

Looks like a nassarius egg pattern, too.

distortus is possible, would need to see the aperture. Given the tiny chained eggs it's definately a species with an extended pelagic period. Could be occulata but the shell patterns from what I see just dont match.

I don't know, Joe. My ceriths have really small eggs and lay in a fairly similar chain and their pelagic period has to be 24 hours or less as they tank-rear fairly well.

True, but the ceriths also have a much smaller body mass. Not to mention there arent too many reports of nassarius tank rearing aside from the RSF species. I was basing my judgement off of egg size in comparison to the adult I probably should have made that one more clear. You should try and document the pelagic period Andy, I know it's a pain but it's super good information!

The ceriths get pretty big. Easily 2-3 times the size of the collumbellids and the collumbellid eggs are easily 2-3 times the size of the cerith eggs. The ceriths just start their meta at a much smaller size.

I still see them from time to time, but it's pretty rare. Unfortunately, I've seen the amphipods prey on the eggs and I suspect they prey on the newly settled juvies, too. The juveniles are _tiny._ I think I have a picture around that compares one to an amphipod. Easy pickins'. The ceriths would be perfect for a dedicated rearing tank. Maybe in a room with a lot of light for algae.
