Domino Damsel Hi Bob, I have a question for you. I have a 120 gallon tank with excellent filtration. I have 5 damsels in there. They been in there for 6 weeks. They have all been quite active and look healthy and eat well. The color of the dominos are reddish black it is more red around gill and face area. They are not jet black. <This species does have "races" (geographical varieties) that look quite different than what folks consider/see as "typical". Please see: http://www.wetwebmedia.com/dascyllu.htm for some pix of variations in Dascyllus trimaculatus> They been like this for as long as I known and they act very normal. They were doing great up to November 6, 2001. Then on November 7 I only noticed four damsels swimming around. I got nervous so I moved some of the decorations around to see if I could find him, and I did. But when he came out his skin was whitish black and he was swimming around very strange which I'm positive was not normal. Then he just laid on the bottom lifeless, so I decided to remove him because I knew he was not going to live. What's wrong with this fish? Is sick? <Maybe just changed color from stress... perhaps just from getting stuck in the rock work. Maybe "changing" color with age/size...> When I bought the fish they were quarantined for 2 weeks before being put in the tank.  <Ah, good> I didn't notice any unusual marks on him., I only noticed a spec on his eye but that look rather okay. My ph is very stable and doesn't change at all. I also have a 16 watt UV as part of my filtration. Please respond soon. Thank you. <Likely no need to worry, "do" anything here. Bob Fenner>
