I have a Veiled Chameleon that is around 6 months right now. I know calcium is important and I dust the crickets that I provide him with "Rep-Cal's phospherous-free calcium with vitamin D" I also feed him dubia roaches and when I can find them, silkworms. I have been told that silk worms are a great source of calcium but have been reading alot on how phoenix worms are great too. My question for al members is this. Are phoenix worms better than silk worms? Also I saw a nutritional chart that shows the phoenix worms are high in phospherous...yet the dusting powder is phospherous free...whats the deal?
