I don't know how big of a cage you should get.
the day I was told was about the as yours but I have a veil cham.
When she is scared or stressed out she will change to a darker color.
I use a ceramic heat lamp and it works the same way as the basking lamp but I keep that on all the time.

Well brad answered it all but you might also try letting the crickets roam free to give him the excercise invovled in catching the crickets. I have a veil cham to and notice that he has a really big appetite. So it just depends.
They covered most of it but hieka I have only heard of veil chams living to be 7 years. I rather like the 10 years better though because I also have veil. Oh and the animals you listed like the moths and stuff can be eaten.
I'm not surprised either. If the is really small it might find it intimdating but because of the size of your cham I think it will eat a lot of big bugs.
most bugs will work just find out what they are first. Make sure thier not poisonous.Roaches, meal worms, some plants, moths are some bugs they can eat.
They are a good source of nutrition for chams. I haven't tried them yet but I will once my cham gets bigger. You can buy silkworms at coastalsilkworms.com. Hope this helps!
:confused: My chameleon is eating six crickets a day and she is the size of my thumb(not including the tail). I need to know if i'm feeding her to much?
