Yet another ID question

[BeachVacationer]

This tiny polyp of some kind came on the underside of the plug of a frag I bought yesterday. What is it and should I remove it if it's going to cause me problems later.

I now have 2 types of frogspawn, a xenia, GSP and a zoa frag in this tank.

It's the brown one in the middle of this picture on the rock.

Looks like mojano anemone or a predatory nudibranch. Either way I would remove it.

It doesn't have that round disc shape but you're right better to get rid of it now than later!

Thanks!
