Smokinreefer,
Theres quite a story to tell with this fish. It was the second fish added to my tank about 3 years ago. Mine was a female, white body with black spots. I had, and still have, another wrasse in there a Coris Gaimard which like the leopard, buries itself at night. The leopard eats all the standard fare; brine shrimp, chopped krill, mysis shrimp, bloodworms. Not keen on flake but will eat the sinking pellets. Throughout the day you will see it cruising in and out of the rockwork, they also like to dive into the sand every now and then and jump out seeing if they've exposed anything edible. Both wrasse do that.
Anyhow, I had a major catastrophe the Christmas before last and lost all my fish except for the 2 wrasse and a damsel due to unknowingly using contaminated water doing a water change prior to going on vacation. The whole tank was pulled down and the survivors put back in the same day. By rights all the fish should have perished but the leopard was one that came through.
Heres the interesting thing; the tank was a FO at the time and one of the new fish I added months later was a small spotted grouper. From day 1 the leopard started harassing the little grouper, sort of coralling it in the corner of the tank, but nothing too serious. A few weeks passed and I noticed that the Leopard started to change colour, with green overtaking the white body. Then the spots gradually faded out and were replaced by a checkered pattern, at the same time a red spot appeared on the dorsal fin. I'm thinking "what the hell is going on ", anyway after doing a bit of research I found that on the reef there is usually 1 male with a harem of a dozen or more females. Should the male die or disappear, one of the females undergoes a gender change and takes over the harem. Obviously, my wrasse had viewed the spotted grouper as a female of the same species and decided that it's purpose in life was to become a male.
Today its a mature male, and a beautiful fish at that. I've got a digital camera and have a photo of it as a female and I will take one of it as a male... I'll figure out how to post the photo.
Don't let anyone tell you that a leopard can't change its spots !!.
Sorry for the length of this post but I thought it needed some explaining.
