Snail ID

I have these snails in my refugium, I only saw one at first but there are at least 3 now. The shell look kinda like a turtle shell and they move very fast for a snail.

 

Hard to tell from the pic but looks like a limpet to me.

 

Very hard to see with your picture but it looks like a Stomatella. A great member of your cuc!!

 

I'll try and get a better picture, my camera is always flat when I need it.

Are these guys better than turbo snails? I am thinking about putting them into the DT as they are in the sump now.

 

Im gonna weigh in stomatella from your description, the pic is tough to go on!

 

+1 on the Stomatella snail. Based on your description alone

 

I agree with stomatella. If you have shrimp in your display, they may eat it. We had a cleaner that ate all of ours in the display, but we have tons in the fuge.
