i have no idea what this is

i have this thing i found in my tank. its always near a coral but it doesn't appear to effect it. i have never seen it move and thought it wasn't alive till i but it on the bottom and found it back on the top of the rock next to another coral. please let me know if its safe to keep in my system and what it is.

 

sundail snail? Zoa predator

 

thank you after looking up some pics im sure thats what it is. its kinda a cool looking snail too bad it eats zoas.

 

sump it if you can (though chances are it will probably starve to death there as well since its a active zoa predator...) or return it to the LFS, I would avoid killing it, but thats just me....

 

Interesting. Never seen one before.

 

i put it in the sump. are zoas the only thing i eats?

 

im no snail expert but I think so yes

 

Good call by putting in your sump. FYI this is a good hitchhiker guide...
