John Courteney-Smith is the Reptile Products Manager at Arcadia-Reptile. It is his job to push captive husbandry as close to optimal health for our reptiles and amphibians as possible – and make that products that allow this to be carried out. He is also the author of a set of books which address the many aspects of keeping healthy reptiles in captivity. Last month, in episode 55, we discussed his first book, The Arcadia Guide to MBD and its elimination in captivity. And if you haven't heard it, I suggest going back and catching that one! Today we are going to go over his second book, The Arcadia Guide to Reptile and Amphibian Nutrition. It is a huge topic and will not fit in one podcast so we will break it up. This episode we will concentrate on vitamins. Of course, all vitamins and minerals work together and must be in balance so it is impossible to discuss one without the other. There is a great deal of overlap!
