Blue Fin Chromis Turning Black! Why?

Ok. I bought 4 blue fin chromis for my reef. After about 2 weeks, one of them turned completly black. Now, two more are starting to turn black. Does anyone know why? They are very healthy and eating, swimming, etc.

That's what they look like as adults. FWIW, I have never heard them called chromis, they are damsels. The Blue fin damsel is also known as the "black" damsel, because they turn black.

They start off mostly white with blue and yellow highlights, but turn to a drab black as they mature and approach their full adult size of seven inches

Ok...thanks Laura . I guess I need to get to a fish trap. In 7 years of keeping a reef, I've only been spanked a handful of times for improper research. This is definitly one of those times.

Thanks again,

Actually, even the scientific name (Neoglyphidodon "melas") means black. Sometimes you can look at the meanings of names to find these things out.
You've done it now, haven't you?
