Yes, they are changing colors.
Michelle, some neat fish to get for Kaylee would be some schooling fish!! Cardinal or neon tetras are neat, but not very hardy. Cherry tetras are tho, I think. And if you get like 6 of them, they should school and they wouldn't hide as much as a single fish.
my little rams are young, so they change as they get older, and my african cichlids are also changing colors. Well just 1 is, the dominant male. He's going to be gorgeous! He looks a bit freaky right now, because his colors are just starting to come in. But he's cool.
