Thanks! No, I'm not concerned about anything. I was just wondering because there are lots of chameleons in my garden and I like to give them names and tell each one apart. And just yesterday I found one which looked VERY similar to another, apart from the spikes on his back were slightly different, so that's why I was wondering [emoji14] I haven't seen him for a while, so he could have had time to moult, if that would change anything.
