Yellowtail Damselfish GALLERYMicrospathodon chrysurus
The Yellowtail Damselfish doesn't always have a yellow tail. The Juveniles are often called "Jewelfish" because of their neon blue spots. As young juveniles, their tails are without any color at all. Adult males will turn yellow during courting. It seems that the small neon blue spots never go away but get smaller and fade as the fish gets older. Look for Jewelfish hiding in Blade Fire Coral. The juveniles are much more nervous that the adults. I guess if my coloring made me glow, I'd be a bit nervous to. Like most Damselfish, they are constantly on the move, darting in, out and around their small, home territory that they will defend from trespassers.
