orange nudibranch lookalike

[rhonna]

I recently found an orange nudibranch looking thing on one of my corals and am not sure what it is. It has no antenas and does not look like lettuce (like a normal nudibranch) but has what looks like star polyps on its sides and is flat in the middle. It seems to shy away from the lights when I turn it on and my leather has not come out since I found it crawling on it. Any ideas? I want to take it out asap if it is what is bothering my leather.
