I'm so sorry about your loss!!
I had a similar experience with a baby chameleon. I was doing everything right. The little guy was doing great for months but then I moved and he started to slowly deteriorate. I took him to the emergency vet and he passed away there. I love chameleons so much but I am so afraid to get anotherI know I was doing everything right, I did all my research and had a perfect setup and talked with the people on chameleon forums, but the little guy was just too sensitive to the move. I felt so bad. I was bawling at the vet over this tiny little creature. That was over a year ago and I am still wary of getting another. If I do I want an established adult.
Anyway! I think a T8 with a divider would be great for 2 males. RHP is also a good idea.
Welcome back!
