Thanks Fish Newbie....I may have been overaggressive in that when I first got them, I was feeding them with 'large' pieces of squid, not realizing that corals that need food to eat, digest it like other animals and add to the bioload the same as fish. Hence, I've been battling nitrates since I added them...not super high, but climbed from 5-15ppm. I'm back to increasing the frequency of my water changes. I tried Cyclopeeze on them the other day and they took them....I think this will help..smaller portions. Thanks for the input and I agreee...as soon as 'food juice' enters the aquarium, they pop open now. SH
