Crocea not fully opening

[REEF-DADDY]

Mine was doing something similar, under 14000k, and when I put him under 6500k iwasakis, he opened up huge
Look for pyramid snails, and sit back and be very still, and watch for anyone nipping at him. I had to do that and finally after about 1/2 hr, saw my bicolor blennie nail him 3 times in quick succession. It took me 1 hr to get the blennie out, and now he's great!

Yes about 2 weeks ago, I added another powerhead to the tank. I am going to move the clam to the less turbulant side of the tank tonight.
