Your temps are too high, and splattering poop usually means parasites. You need to get a fecal to a Vet, and more than likley the animal to the Vet. I am highly doubting you have a CB animal there. What are you putting in the bug juice?
Here is some great advice from someone near you!
Misting more to keep temps down can be a bad idea in glass, it will create such high humidity that you could end up with respiratory infection coupled with the fact that the water has no where to go in an Exo. It sounds like you seriously...
Well, being in Canada I don't think we can say no glass, but we can say no Exo if it is too small for the species you want. You may have to look into customized well ventilated glass enclosures.
JJreeb-what part of the country are you in? It has alot to do with the kind of caging you should use. There is not an Exo large enough to house male Veileds or Panthers, and housing females in them is iffy. Some Jacksons are quite big, and utilize much of their cage space, and I do not...
Jjreeb-we are a passionate group! Please don't take all of the well intentioned advice the wrong way-it is easy to do that when on a forum. Waterfalls are simply more trouble than they are worth! Chameleon love to poop in them. If you have the mister you are more than good to go.
With the amount of misting is requires for these animals, you will soon find out that no substrate is a better way to go, not to mention that many substrates are an impaction danger. Your cham will quickly outgrow that Exo, and you will want to eventually have him in something at least 18X18X36...
"Tame-able", waterfalls, smaller glass cages? Research is needed here. Jacksons are a chameleon that need high humidity and decent air flow, and I definitely do not suggest housing them together. Waterfalls are a big no-no in chameleon land, and that glass cage does not provide the vertical...
Whoa-Kill both of those 100 watt bulbs-no wonder you are concerned about dehydration! You only need one 60-75 watt bulb in one corner of the cage-which should give you a nice basking spot of around 85-90ish degrees.
I do not see a UVB light-which is essential. What kind of bulb do you have in the clamp lamp? What are your temps? Do you have substrate in the bottom? Mealworms are a bad staple feeder, and a young cham should be eating 10-15 well gutloaded crickets daily with the proper supplementation...
Chameleons are generally solitary, territorial creatures that do not care for and are stressed by interactions with ANYTHING-humans and other chameleons included. Since you are new to chameleons it might be helpful to make sure your husbandry is spot on to avoid future potential problems...
