Based on colors and patterns it looks like a female to me. If she is captive bred/hatched the pet store should have an idea of the age. This species is SHORT lived 18 months to two years(max). They are really cool little guys. Just gotta be prepared to not have them long.
Good luck if you decide...
Good morning,
Other than upping the basking temp to the low 90's, and listening to the Chameleon breeder podcasts about Carpets I do not have much to add. Most has already been suggested. Smaller feeders, and more of them. 1/4" crickets, ex small dubia, and if you can find them tiny horn worms...
This is Poncho. Chihuahua-Minpin
Gennady is chihuahua mix, and the little guy is Loma. He's an imperial Shi Tsu.
And our Whites tree frogs waiting for breakfast.
be cautious about free feeding the hornworms. They have a very strong grip, and have been know to dislocate chameleon tongues occasionally. I only hand feed them, or have them in something like a tuperware so they can't hang on when the cham tags them.
I've mostly seen Drylok used on carved foam backgrounds to seal them, and allow a paintable surface. It is a masonry sealant, so not sure how well it would work on wood. The flex seal is basically just a liquid rubber.
For waterproofing?
I used flex seal. put on 1 gallon, let it cure out, and then used a pint to build up the corners and help move any water to the drain
Fox farms organic is a good alternative.
You can mix your own, but I have never done it before.
Really I think any well draining organic potting soil would work

Welcome. Link is in the post above. Downspout outlet. Just make sure you seal it in with the silicone, or whatever else you're waterproofing the planter with
