Welcome to the forums. Any photos of your chameleon and his enclosure?
I feed dubia, discoids, crickets, silkworms, hornworms, Phoenix worms, super worms and grasshoppers. Not all at once. I rotate around but always have 3 or 4 feeders on hand at all times.
You need to gut load the feeders with greens they are excellent. You can use collard greens, kale, bell pepper, carrots, butternut squash apple and orange. You can also buy a premixed dry gut load such as Cricket Crack.
The feeders have to be "lightly" dusted with 2 kinds of supplements. When your chameleon is young you will use plain calcium (no d3) at just about every feeding...... if you skip one or two days a month that's ok. You will also need Reptivite with d3 twice a month.
