Hi im pretty upset right now, i know chameleons are really aggressive and so when being handled at times and espically dont like it, i had gotten my chameleon since and im just a high schooler who lives with my brother and i put a lot of money into this normally myself and my brother split it but its always more 2/3 me paying because i make more and my chameleon had seemed to like everyone in fact, but about a week ago hes changed he is now about 2-3 months old i feed him everyday always clean up his enclosure and everything and i hold him like once every week or two only normally when i have family over or something and he hissed at me, everytime i try to pick him up im hissed at, now the average chameleon keeper would think hes just picky and dosent want to be held well think again, everytime my brother goes to pick him up nothing he dosent care or anything. Its quite upsetting espically whenni confirmed it my brother picked him up today and i was like let me hold him to see if its just a personal thing getting him out of the enclosure and he hisses at me, so long story short my chameleon isnt mine anymore... ive associated myself in every way possible with him feeding cleaning his enclosure and everything but the only reason i could think of why he adapted to my brother more who has done absolutely nothing is there were 2 seperate occasions which occurred within the past month or two where he has had to care for him for about an hour or two while i modified his enclosure (once was to add a humidifier, the other was because i found mushrooms and i had to clean the entire thing out). Let me know your thoughts, ways to fix this/avoid this. Thanks.
