I usually feed my ousties a mix. Each week they eat 3-6 adult dubias and about a dozen crickets. Sometimes I spice it up and get hornworms or silks too. My guys will keep eating if I let them so I try to give them a good balance without getting too fat.
I have a verrucosus similar to yours and when I first got him I fed him a horn worm and 6 crickets and he got fat so now horn worms are snacks when I get them. I feed 6-7 Medium crickets everyday. Hes around 7 months and starting to get back to normal weight.
How old is your chameleon? In your avatar he looks sub adult (ish). Along with a variety of feeders the diet should be a well balanced gut load for your insects. What are you feeding? What are you gut loading with? This is important. I feel having a more balanced gut load for your insects to eat is more important than the whole supplementing with calcium every feeding and general rules with that whole jargon. Supplements are needed but I think if you can get your cham more nutrients naturally its better than supplementing the natural way with supplements Its better for humans or any other animal to get the nutrients we need through the natural way not a multivitamin.
