i can't get a picture right now, but i did read the reefkeeping article and they don't look like those snails in color at least, it's hard to tell because they are so small. they look like baby astrea cerith and nerite snails like the rest of the snails in my tank so im pretty sure that that is the kind of snail that they are, my main question is whether those snails will pester or stress the clam in any way. it also shouldn't have pyramids because i got it from diver's den and they QT their stuff for a month or so
