Need a ID on a hitchhiker please

[Josh jones]

hello so I walked into my house and I always go to the tank just to check on it but then I noticed this little guy on the glass and this is my first time seeing him. Should I take him out or is he ok in there and what is he?

Nudibranch 90-95% of them are bad or will not survive because they are so food specific. More than likely a zoa eater.

I would remove it if you have or plan to have coral
