I don't know of anyone who has set up a breeding program for graceful chameleons. There is a need. They are beautiful chameleons, but they are almost always WC. You would certainly be doing a service to this underrated chameleon species if you decide to do it.
got very interested in this "new" species (new to me) from this forum, and found a lot of great info by typing graceful chameleon into google, you should check it out. this is a very reputable site I listed though
