Many fish are able to change the way they look based on different factors - stress, mating behavior, excitement, etc. I think of it as people when they blush, only fish can generally do it across their whole body and for many more reasons. You'll also notice, in general, fish will be much lighter first thing in the morning just before and just after the lights come on. Perfectly natural.
