I noticed this creature moving around today. Is it harmless? Should i let him stay? What is it?

Looks like a nudibranch, and if I had to guess I'd say of the green star polyp eating kind. Regardless, these types of sea slugs exclusively eat polyps of some sort - remove it immediately!

Looks like a nudi of some sort. Id take it out until you can get a better idea...something like that can easily disappear then your stuck.

Generally they are bad guys and it depends what corals you have that it might feed on. Worse actors are zoa specific and , monti specific. But there are also aiptasia specific ones that folks buy and sell to deal with those . If you see one there are probably more.
