Hey Dustin, I think the decision to get a wc pygmy is the same as getting anything else wc. My thinking is that because of their size they would be very difficult to treat if something went wrong. I think most people do trios -- 1.2, but if you have lots of space, then 1.3 is probably ok. I like to have enough room that if they don't want to see one another, they don't have to. They seem hardy enough, but again, because of their size things can be more difficult to notice than in something larger. I think they change colour a lot, though I have not had the pleasure of owning a blue or pink or red cham, so I'm speaking colour change relative to pygmies. My female sports all kinds of dots and stripes, then goes to dark or light grey. My male is more plain, although he goes anywhere from a mossy green grey to a very dark grey (if he needs to warm up, or I'm taking too many pictures). As for activity, some days they're all over their enclosure, sometimes they spend 2 days on the same twig. I heard that's normal. The only other thing that I feel is important is that they be looked after the same as any other cham or lizard, in that just because they are cheap to buy and little in size does not mean that they don't deserve the same vet care and general care as the larger chams. Not to imply that YOU wouldn't, but I wanted to put that out there. I will let someone with more experience speak to the parasite issues. I assumed that mine were wild caught, but I don't know, and I put them together right away. That was this past summer, and they are happy and healthy. So far she's laid three clutches. They have turned out to be my favourite type of cham!
