What are the white dots?

I'm looking at the white bubble-looking dots on the snail and the rock. They are also on other rock. I haven't seen this before tonight. I'm sorry the pictures are not the best, I'm new at this.

 

probably a sponge. http://www.3reef.com/forums/id/common-ids-43555.html

 

nope they are micro turbo snails!..i have a billion of them!(j/k)i do have a lot.

 

if they move hes right i assumed they were stationary

 

They are like tiny turbos, but stay small. I can't remember the name right now, too much Gin.
But I'll give you the link tomorrow.... They are cool though

 

jptrson- thanks for the snail idea- I found an archive on the site about nerites, looks like what I have! I don't think my tank produces enough algae to support them, so if they die, am I in for pollution?

 

try here Xtalreef hopefully COLLONISTA SNAILS and not the pyramid snails
