i have read a couple of general care sheets for them. what i was hoping for was more of a compare and contrast in husbandry with more common species like panthers and veileds. and more importantly personal experience with them, like their temperament and handling.
Melleri are really quite different in their space requirements and they will need lots of water daily, lots of larger food items compared to a veiled or panther. They are strong and heavy, so will need larger sturdy trees or shrubs in their space. Even the typical Schefflera will get damaged if that's all you have for climbing. I used Ficus alli trees and any of these plants large enough won't be cheap. Sometimes you can score a big overgrown houseplant at a moving sale. Also, you can add to their habitat by using larger fake Ficus trees with real tree branches to connect them. If you really want a melleri be prepared to give them a large living space in your home, not just one additional cage next to other animals you happen to have. They deserve this at least. Personally, I won't keep another melleri unless it is free ranged. Mine were so much happier (well, contented and healthy) that way. Some refuse to adapt to cages, others seem OK with it. Other than that, they need the same basic things like basking light, UV light, humidity cycles, live trees and shrubs, and correct dusting and gutloading feeders. In terms of handling and temperment, they are just as individual as any other cham species. Nice ones are almost a social pet, stressy ones can be terribly shy, and nasty reactive ones can be vicious. Some of the extremes are simply due to their larger size and strength. For example, a good bite from a melleri can blacken your thumbnail and do some real skin damage. I"ve got a couple of scars from a wc rescue to show for that.
If you want to devote a lot of daily attention to a cham for years, this is a great species to work with and very rewarding. But, if you are not settled in your own home for the long term or can't make modifications to a rental to suit a free range cham (hanging UV lighting from ceilings, bringing in large tub-potted trees, humidifying a room, installing an RO water filter, running auto misters in a room), it will end up being a lot of work and frustration.
You've gotten good references and the melleri discovery link. Spend the time to read and you'll learn what you need to make your decision.
Oh, and about sexing...they are almost impossible to sex visually. With luck you may see a male show his hemipenes during defecation, but that's about it. Temperment wise, I doubt one sex is different than the other, and the females don't have the same problems producing infertile clutches. If you don't get a juvenile from a quality breeder most others available will be wc. A wc juvenile won't have the heavy parasite load a large adult might, but be ready to test them for parasites if you do go that way.
