we have Rango on a multivitamin and i am going to get some calcium tomorrow, the vitamin we have has everything in it but have been doing some reading and it says to give juveniles calcium every day, looking for opinions. our guy is about 6 months old, guessing here. but to me he doesnt seem to be growing so maybe hes younger? my husband says hes growing and my mother in law says hes growing, maybe to me he doesnt seem to be because i see him everyday but i dont know. hes healthy and very active, drinking water and eating like he should be so i may just be paranoid since we are first time chameleon parents.
