Help !! Dommino not doing well

[Captainhemo]

Hi,

Sorry for not mentioning tank details, just slipped my mind a t the time. Wos worring to much about the fsih
Yeah, they are Domino Damsels but it is more like the other way around. The stressed one (larger) is putting the run on the other (smaller).
I've had these fish for about 3 weeks and they have been doing well. The larger one has always apperaed to be the dominant one but last night she was really aggressive Both fish have always eaten well, (mysis) , there doesnt seem to be any change in her appitite
The tank is 33 gal, those are the only 2 fish. Also have numerous hermits, a few snails 40 lbs live rock / 40 lbs live sand.
Tank levels are 8.2 PH, 0 ammonia, 0 Nitrites, < 10ppm Nitrates, Salinity 1.023, temp 78. The only newly added items are 10 days ago I addded another 10 lbs live rcok and a small rock with a red mushrrom and what appears to be a yellow center Zooanthid.
Looking in this am, the fish appears to have regained much of its color, its very strange. She also seems uch calmer today . I ahvent turned ont he lights yet today so she may appear to be a bit "paler" once that happens I cant believe how she seemed totally normal when I left for dialysis ( i fed them just a bit before leaving so I know she appeared fine) and was so different when I got home about 4.5hrs later. She seems so calm right now I'm scared to turn the lights on
