Bell pepper, carrot and squash should not be fed everyday but once in a while. I am not sure about the other ones, so I will let somebody else answer you on those ones .
Take a look at the link Murdocjunior gave you, it really helped me finding ideas
I changed their diet today so far so good, I also added mazuri on their diet, I'm gonna give it to them once or twice a week. Thanks Murdocjunior, Tortielover, and Isa!!!
