I get the "Can O' Mealworms" at PetsMart in the reptile section. You can also soak them in fish vitamins (or inject a few drops of vitamins into the mealworms) to get vitamins into him/her. The tiny size works great for baby Severums. It's the only thing my Severum ever ate from my fingers when he was a baby. Let him see them drop a time or 2 until he figures out what they are. I hope he likes them. Brine shrimp to fish is like potato chips to kids. No nutritional value but they love them. They work great as a laxative if the fish gets constipated for future reference lol
