It's been a while, but I went to my vet (She's absolutely amazing! She has over 40 years experience with reptiles, and over 25 with exotic reptiles. My chameleon honestly hated the ride over there more than actually interacting with her) I told her about everything, and got him tested (all cleared) I've made some adjustments to my care, but the vet doesn't think he's going to grow anymore. She gave me a few guesses on what happened
1. He's just a dwarf chameleon (I'm hoping for this one)
2. She had someone recycle an old UVB bulb, and they had a similar problems. The way she described it to me is they didn't have enough UVB to properly digest their food... So now I'm paranoid that someone's returning used UVB bulbs instead of paying for a new one, and I'll now be ordering directly from a manufacturer.
3. I swear there was more but I just can't remember, she also thinks I did a bad job explaining the food situation to you (tho I have made changes based off of her suggestions) I would like to thank you for your help, and look forward to interacting with you in the future!
