Just read the bad news.. I am so so sorry he passed away. My heart goes out to you, for I have lost one myself and know how it feels - the pain was excruciating, especially because I knew it was my own fault, didn't matter that I did it unknowingly because of lack of experience. It still hurt as hell. Yet, I urge you not to blame yourself. As many pointed out - chameleons are not exactly easy to care after, especially for a first time owner. I suggest you do your research and when the right time comes, get a new one and do your best to provide it with a good and loving home.
