Yes, the kids (teens) joined various chameleon groups to read up before we got it, which was bought from someone who'd looked after it with supplements etc so it was healthy, but it needed a bigger viv and they didn't have the space.
Even with a 5' mesh enclosure, separate UVB and heat lights, regular spraying, a supplement routine and lots of cover, it was miserable and cold.
Turned out we had too much cover, the UVB wasn't getting far enough down the enclosure. That took three vet trips to figure out - totally fine at the vets but when we brought him home he'd stop feeding and go dark.
We bought a mist-king too - the constant monitoring of humidity was too hard to keep on top of. And they went bioactive, having plants growing in the soil really helped - there's still a lot of plastic plants in there but we're gradually taking it out as the gaps fill.
It's a grumpy, aggressive, ungrateful animal. It's nothing like Pascale at all, and I worry that most have miserable short lives - we got it wrong and the kids had experience with reptiles and really did the work, research and bought the kit before getting the animal.
He is rubbish, but, they love him. I think of it as a very expensive and very large, lamp for the dark corner which disapproves of me (good grief, it can throw some shade when I come in the room!).
