So, Im heading out to a reptile expo soon, and I plan on getting a chameleon. I'm really set on a flap necked chameleon, but if they didnt have one, Id chose a carpet or veiled. I have a 2' x 2' terrarium with a waterfall. Im wondering, currently I have coco fiber substrate in there but Im not sure if thats okay for a chameleon. I need all the info I can get. Thanks alot!
