Need help/advise

[Nemain]

My Anthias is still in hiding, he still comes out to eat. Now my lawnmower blenny is doing the same, but not eating. They arent moving, they just sit near the bottom of the tank.

I am going to pull them out of the tank today for QT,my main concern is that my QT is only 20 gal. Not so bad for the blenny - shear hell or the anthias (He is only about 2" long now).

My other concern is that I have no idea what is wrong. Corals are all thriving, anenome is thriving, and all the other fish are still fine.

I don't want to put them in QT to just watch them die =(

ANy idea's/help would be fantastic.

Thanks,

Beth
