You did get quite a bit of not-so-great information from the seller. Proving gender by x-ray is not conclusive and a rather expensive test, so doubt it. Sometimes the most simple observation works...watch during defecation. Over time you may see hemipenes and will know its a male. Ear flap spots, size, coloration are not conclusive. Sometimes ear flap size can tell, but you need to be able to compare your animal with lots of others. The cage you have is much too small, so be ready to either free range it or build something at least 6'x6'x6'. Some melleri won't tolerate cages of any kind. Don't feed it pinkies much at all. They are high in fat and not that nutritious. Not a very natural prey. If you want to feed vertebrates to melleri it is suggested that you offer fledgling birds such as zebra finches. If you get to know a local finch breeder they might be willing to give you nestlings that won't make it because of abnormalities. They are a good source of zinc, and if offered in a fake "nest" nestled in a tree can be very welcome. CBB melleri are extremely rare even as babies, so one offered as cbb that is that large is again, rather doubtful. Lots of dealers have caught on that people want a cbb melleri and often just pass theirs on as such. A "dog tame" melleri may just be malnourished or so stressed it does not show it's natural behavior. Most melleri are not that "nice", but some are very gentle. They often charm you by climbing up on your head or shoulder without gaping. Well, they are just trying to get up as high as possible, not being friendly. A larger melleri can easily knock over most feeding dishes as they are incredibly strong. The force of their tongue can knock large prey right out of your fingers! Try using a clouded plastic storage bin or box for food instead. You can easily hang the box in the trees so it can't be knocked over. Their tongues can easily reach 1.5 to 2 feet away. Their bite can blacken a thumbnail and grip can numb your fingers. As for other great melleri info check out the melleri forum on YahooGroups, and a website called "the Melleri Discovery". I don't have the address handy, but you can link to the articles from the Yahoo forum or use Google. It is very new, and Google should find it OK. There are also some articles about melleri in past issues of the Chameleon News e-zine at www.chameleonnews.com. Be ready for a "crash" in health at about 3 months. Melleri are often called the "90 day chameleon" for very sad reasons. Just when you think they are acclimated, they stop eating, develop problems, and can refuse to thrive. Often it takes months for all the accumulated stresses of a move, sale, shipping, etc. to show up as they are very tough and secretive. Really neat species, but they will be more demanding than most others! Join the forum...the best group working with melleri around these days.
