Can African Fat-Tailed Geckos Eat Mealworms?

Protein is decent but fat is considerably higher than dubia or crickets, and the Ca:P ratio of 0.04 is the worst of common feeders. Their small digestive tract means gut-loading has limited effect. The main advantages: cheap, widely available everywhere, refrigerate to extend lifespan for months, and geckos love them. Fine as part of a varied diet — just don't make them the majority. Giant mealworms are treated with S-Methoprene (insect growth regulator) — research this before deciding. Fat-tails gain weight easily, so keep mealworms to a minority of the rotation and watch tail thickness.
