Chameleons are fantastic pets... They can be quite difficult and require a lot of work, but for me, thats part of the attraction. I love to see them thrive after all that hard work.. It part science, part art, and part manual labor
Sounds like you have a lot of time to reasearch, decide, and prepare for your new little buddy. Here is a great place to start. These are caresheets for different species of chameleons you may be interested in.
To address some of your questions:
- Chams can be in the same room as a beardie. Probably best that there is a limited line of sight to prevent stress in the chameleon
- Best staples besides crickets are probably dubia roaches and silkworms. A wide variety of well gutloaded food is the biggest single factor in chameleon rearing success and no single feeder should make up more than 40% of their diet.
- Flightless fruit flies will be too small for most chameleons except babies. Blue bottle flies are a great option for variety.
- the caresheets address feeding, but basically they can eat all they want when they are young, gradually reduced to 5-8 bugs (equivalent to adult sized crickets) every other day. Species and gender play a role here, so the care sheets are a great resource.
Enjoy the research and preparation and we will be here if you have any additional questions!
