Hi,
I've kept and breed them. If you can handle chameleons well you shouldn't have problems with them. For a 1.2 group I recommend a enclosure with minimum 40x40x60 cm. That's minimum. Sometimes even the females are terretorial. They could be productive so look that the females have good ca+ sources.
For the juvenils you need very small food, little drosophilas and fresh hatched crickets are the best
