need help. this is a hard one...

i cant get a picture of this this but a have a fairly good description.

it looks like a 1/4 inch snail with a flat shell on the middle of his back. they only come out at night, and i have not seen them on any of my corals. the body is a pale whitish green, and the "shell" is brownish green.

same face as a turbo snail, but what is with the shell? and if anybody knows what these are, do they eat coral?

 

Sounds like Stomatella varia. They're good guys.

thats them! and karma to you kind sir!

 

You're quite welcome.

One good thing about them is that they will reproduce in your tank but will never overpopulate. They eat microalgaes non-stop.

 

great!
