 Are these reef safe?
My camera is not very good, and I don't know how to turn off the flash.  .
Well, here goes a description.
K. I have about 8 of these slug like things in my tank. They have a mix of white/tan/brown stripes running down their bodies. They also look to have an external type shell that seems to small for their body to fit into.
I also seem to have one of those crabs BL had in her fuge/sump thing. 
On a good note, I seem to have a hawaiian feather duster that came in on my new rock, as well as a pretty black/blue feather duster. I also have what look to be 3 button polyps with green centers.
Just wanted to make sure these snail things are reef safe, and won't eat the coralline or any coral.
