What is this

My clam passed away, I put the shell in my sump and 2 weeks later this is on the shell, any thoughts?

First off I do not actually know, but it seems like a Nudibranch possibly. Does it move around, and slide like a snail or skitter like a pod?

It’s attached to the clam shell, does not move.
