I'll just stick to pellets to be safe lol.Live food is not the healthiest choice either. Easy way to transmit a disease into your fish. No goldy feeders!!! Stick to pellets and give treats if you want sparingly. Frozen fish, shrimp, and the like is fine as treats. Worms and insects as treats only if you are 100% sure they haven't been exposed to pesticides. They will also take some fruits and veggies. No mammal meats.
What veggie is good to feed him?
