baby jumbo ceriths?

I got a CUC several months back and part of it was 5 jumbo ceriths, which I barely ever see cause they like to dig through the sand during the day, but every once in awhile I see them out eating...so the other day I'm looking at my tank and see tiny snails on the glass, and they look more like a jumbo cerith shell then anything else in my tank, they are small so I dont wanna tank one out and risk hurting it to photograph it. I counted 19 the other day, any Ideas on how many there may be? and if you think some will survive?

 

its had to tell. some times i use a magifying glass in front of my camera to get some close ups.

 

yeah, I think I'll just leave them be, if one gets a bit bigger I'll find out what they are, i have found other babies this morning, some sort of turbos I believe, they are way smaller then a micro turbo but I have micros and mexican turbos so who knows, I also have 9 astreas, so we'll see, I hope they live, I love finding new life in my tank

 

i got a pic of a baby brittle star riding a turbo snail its in invert forms
