I just added a small (3" - 4") Harlequin Serpent Star to my 75 gallon tank. I drip acclimated him for 4 hours with a drip rate of one drop per second. I checked at the end of the acclimation and pH, S.G., and temperature all matched up. I didn't expose it at all to air when I introduced it to the tank, and the color was normal at the time of introduction. I get home tonight to find it's entire central disk a sort of pale white. It looks as if he may have eaten one of my peppermint shrimp while I was away, as I found the head of the shrimp next to his cave. All of his arms still have normal coloration and he seems to be moving around just fine. No noticeable deterioration anywhere that I can see as well. Is this anything to worry about, or is it a normal occurrence? Any help would be greatly appreciated.
