Will a six-line wrass beat the crap out of an orchid dottyback?
 

I am looking to get an orchid dottyback for my 120 gallon reef.

Current inhabitants are 2 maroon clowns, 1 ocellaris clown, 1 hippo tang, 1 yellow tang, 1 flame angel, and one six-line wrasse. I don't see any aggression in the tank except when the six-line wanders too close to the maroon clowns' anemone.

I don't know whether to expect problems or not adding an orchid dottyback. Of course every fish is different but most likely will they get along or not?

Although extremely beautiful, I would not recommend a dottyback for any tank because they are hell raisers. Your is big enough to keep them apart, however as you add more fish aggression will occur.
