Two small what look like anemones ?? I have about 25-30 spreading rapidly throughout my 175.

Mojanos. Zap em stat.

Yep, pests zap em. Lemon juice in their throat usually does the job from a syringe.

I would eliminate all you can find or else your tank will become a majano species tank

A filefish may be nice for some upkeep once the problem is at bay! They don't always go for it but when they do they are amazingly efficient. I saw one wipe out a completely mojano over run 110 in about a week.
Some will nip at corals though.
