Okay I have a young flapneck chameleon that is very friendly. On occasion he likes to enjoy time out of his cage. I put my finger in his cage and if he wants to come out he climbs up it. The other day I had gone out the night before so my nails were painted (I usually don't do that). I put my finger out for him to climb up. He started to climb up then he saw the dark nail polish. He pulled back, put his flaps up, puffed up, and bit my finger. This is the first time he has shown any aggresion towards me let alone bite me. He is so small it was very funny watching him act big and tuff. I couldn't help but laugh eventhough my finger hurt a little.
