So I'm getting a veiled chameleon and need to know what all different types of calcium and supplements that they need and if they need them all the time or when they are growing into adulthood
Congrats on the soon-to-be new addition! I recommend reading this section in the Chameleon Resources, it covers diet and supplements and links to additional good reads if you still want to learn more. If you still have questions then please, by all means post them, but I think that link will answer pretty much everything.
The other sections are useful too if you have questions on housing, temps, water, etc.
