I have a Sailfin Tang and 5 damsels (2 blue, 2Blue/yelow tail, and 1 three stripe) in my 75 gal. I saw some real prettye Purple Queen Anthias at river city Aquatics that I would like to add. I know i would need 3. My question is would i have to remove my damsels to and the anthias?

I have a 75 RR with 20 gal sump 125-130 lbs. live rock and 4 inch sand bed.
