[Kung]

I recently purchased a 2 1/2 inch virigated rabbitfish from an LFS that I respect and trust. I had picked him out on a Sunday afternoon, but had him held until the following friday morning. When I picked him up, he was dull in color, but I thought nothing of it as the lights weren't even on in his tank yet.

It's been two weeks. He eats, he frolics, he does all the things he should do, and yet he remains dull in color. None of the others(seven inch sailfin, a royal gramma, a blue devil damsel, and a lovely coral beauty angel) in my 125 have had issues of any kind. Water chemistry is fine, as I know that dull coloring often is a result of pH issues. Other than being drab, he is completely fine.

Any thoughts? He has been mostly eating the hair aglea from the rocks, as he was purchased to do. He is mostly done, and I will need to find a food to maintain him on. Is there a good color enhancing formula available? I had used Prime Reef a while back, and am feeding the others some old flake that really should be thrown out and frozen brine shrimp. Mostly they pick what they need from the live rock and are thriving at that, so I feed maybe twice a week. Would my little rabbit benefit from some nori or another source of algae to vary his diet?

Sorry for the novel, but I thought you might need to know a lot of that background to accurately answer my questions.
