Reptiles and amphibians have been kept by humans for thousands of years, but modern research has revealed just how complex their nutritional needs really are. As captive keeping has grown in popularity, so too has the responsibility to provide animals with diets that allow them not just to survive — but to thrive, grow, and reproduce. The Arcadia Guide to Reptile & Amphibian Nutrition is a comprehensive, science-based handbook designed to help keepers understand exactly what their animals need to remain healthy in captivity. Written by Arcadia Reptile’s expert research team, this guide brings together decades of field studies, laboratory data, and husbandry experience into a practical and easy-to-follow format. It explores the full spectrum of reptile and amphibian nutrition, including wild feeding behaviour, prey composition, hydration strategies, vitamin and mineral groups, gut-loading techniques, and the interaction between supplements such as calcium and vitamin D3. The book also addresses common feeding mistakes and explains how modern captive diets can fall short without proper supplementation and lighting. Whether you keep lizards, snakes, frogs, or tortoises, this book provides the knowledge needed to build nutritionally complete feeding regimes that support strong bones, healthy growth, immune function, and long-term wellbeing.
