Orange Sea Slug

I received 15 lbs of live rock from KP Aquatics from the keys around one week ago. I noticed this guy hiding during the day and way active at night. Any ideas? Thanks!!

I think a picture of the other side of it would be helpful for ID purposes.looks like a cool find though!

Ditto on the guy above me. I got something very similar looking in my KP live rock and I’m pretty sure it is a sort of limpet. Fleshy limpets are normally good for the biodiversity. Mine sadly passed

Possibly a planocerid flatworm I don't know if they're reef safe but may starve to death if it doesn't have its food source.

Definitely a type of polyclad flatworm.

Thanks guys! I have a picture of its underside now. Any idea of its food source?

It is a frilly limpet and a harmless algae eater. I have one from KPA rock too.

They are nocturnal. Enjoy the free interesting and unique snail.

It looks like this to me because of the rhinophores and exposed gills in the first photo. Platydoris pulchra a type of dorid nudibranch. However since you said this was found on KP live rock in the Florida Keys it isn't the exact species as this one is found in the Indian Ocean. So I suspect yours must be a similar species to this one. Not too sure of the diet but I assume sponges or tunicates.
