Welcome Debi, you made some errors I'll tell you right up front. It is however fortunate that you are seeking help. OK, lets clean the slate... forget everything that the pet store dummies told you. Forget even what the first user (psyensics) has told you. Most of it is wrong. There are many widespread Myths going around between the uneducated or inexperienced. You will enjoy reading the article here called:
Common Myths of Chameleon Husbandry: Cautionary notes for the new chameleon owner and another important article:
Introduction to Chameleon Husbandry
I hope you like reading, you have a lot of homework to do.
You have said both He and She in your post? Which is correct? (For the most part, although there are exceptions) Males have Three horns, and females, either just a single horn, or none at all.
Recently, the yearly chameleon shipments have just arrived from Tanzania, which is where some species of Jackson's chameleon are native to. This means there is a good possibility that your new pet is a Wild Caught (Referred to as "WC") Specimen. You will have to take into consideration that it takes time for chameleons to become acclimated to captive care. Info on this can be found here:
Chameleon Acclimation, where the process of acclimation is described with detailed photos. The text discusses how important hydration is for wild caught chameleons, as well as how to deal with parasites that every wild caught chameleon inevitably has. Captive bred Jackson's tend to be bought up quite fast by experienced chameleon keepers.
Your baby will be fine in a glass tank for a while. In fact many people use solid sided enclosures for Jackson's, or screen cages with some of the sides covered, as humidity is more easily maintained. You can adapt humidifiers to run in systems like the one described here:
Humidifiers and Chameleon Enclosures Glass is however not always a great idea. It keeps heat so well that it acts as an oven
Chameleons do not need a constant heat. Sleeping actually is aided by temperatures dropping. Some people suggest that the ambient night temperature should drop about 10-15 degrees from the ambient daytime temperature. This however is only a guideline. You should not need a night light, or heat source, as long as your house does not drop lower than 55*.
Unlike what the user
psyensics, told you, it is not correct to use a ceramic heat emitter instead of a basking lamp. Nor is it safe to leave it on through the night. Hopefully the user will read this and take this advice as well, because it is an important rule in keeping chameleons.
So far, all the links I have given you have been about specific questions you had. I'll leave you with one more. Here is a bit outdated, but still quite trustworthy dedicated to this species:
Jackson's Chameleon Information.
I wish you good luck. Im sorry about all the links, but there is just too much nessescary information to post all together.
