Hydroids or Aptasia?

[Daddy-o]

Vinegar wont hurt your reef. It is actually a form of carbon that feeds bacteria. I add about 100ml a day to my reef.

Heard Bristletail Filefish will clean up Aptasia. Is it reef safe as I have Zoa colonies?
Peppermint shrimp is not an option since I have a 6 line Wrasse.
Copperband Butterfly will nip at Zoa so no again.
The Nudibranch that eats Aptasias is not available here.
Any other natural Aptasia eater?

I have a 6 line wrasse and 5 peppermint shrimp for what its worth, they'll knock out that in a few days.
