I'm 99% sure you'll be fine. What are you worried about having happen?
I had good luck using a pep for aptasia but it will steal food from your lps if you have any. In a small tank, it could be a bit of a pita. Also have been reported to munch various polyps. I never noticed that with mine. Also, super freakin' fast. Very difficult to catch if you decide to remove. If you get two you'll likely get eggs which is a nice little extra food source for your fish.
Good luck.
