V. rudicollis are native where I live and I have yet to come across a Varanus species here that does not devour frogs. All of the native species that I keep are fed farm raised frogs (Rana sp.) as a primary food source (they are raised for human consumption), with insects, rodents and fish as a secondary depending on the species. Toads are a big problem: all species of true toads, Bufo sp., are poisonous, some more than others.



Lizards are also eagerly eaten. Yes, there is the possibility of parasites, but mine have been fed lizards from time to time. Parasites can come from many food sources, such as rodents and feeder fish, especially if the food is not human quality. Mine are crazy about eating Calotes sp., but I am not crazy about feeding to them, those feedings were mistakes thinking they were to big to eat.



Varied diets are good, they offer a variety of nutrients that a single food source diet does not provide. Yes, single source diets with supplements are good, but varied diets with supplements are even better.
