Some type of limpet

[Mike N]

I've seen this thing a few times over the years. Pretty obvious that there is a limpet shell underneath that shroud.
Anybody have experience with these things? He's been hanging out around my zoanthids a lot lately, just curious if you pose any danger other than knocking frags off plugs.

Looks like a fleshy limpet. Not sure if they eat zoas though

Thanks, that is my main concern. Might just stick him in the sump.

Agree, it's a fleshy limpet. They are algae grazers.
