Things to Comsider
- Remember that Savannah monitors are mainly insectivores, but as they are opportunistic feeders and can eat fish on occasion. However, it’s important not to rely solely on fish as a food source and to provide a balanced diet that includes a variety of prey items.
- Do not cook fish before feeding it to your Savannah monitor, as cooking can cause the loss of essential nutrients and alter the texture and taste of the fish. Cooking fish can also make the bones harder and more brittle, which can increase the risk of injury to your Savannah monitor. In the wild, these lizards would consume whole prey, including bones and all, and have the necessary jaw strength and teeth to crush and digest them properly without cooking.
- Consider other whole prey items in addition to fish fillets. Crayfish, for example, are a good source of calcium and can be a better choice for providing this essential nutrient. Crab, scallops, and shrimp can all be fed to your pet Savannah Monitor, and most types of seafood with shells, such as mussels, clams, and oysters, can also be fed to your Savannah monitor as a source of calcium.
