Dear candidate

Piranhas when living in the wild or out in the seas or other water bodies they will have a different kind lifestyle or verity diet but it will be different for those same ones in the aquarium so, i am mentioning few types of food to feed your baby piranha

• Fish
• Shrimp
• Mammals like small one like baby rats
• Insects that are live and not diseased or dead like crickets, meal worms, mosquito larvae etc.,
• Worms, safe and live worms which dont have any disease
• Frozen foods, there are the one that are specially made to feed fish which you can buy in pet store
• Frozen cubes like feozen meat like mainly small fish and other meat
• Pellets/ sticks/ flake food like foods with low in protein, calcium and vitamins like very light food
• Meaty foods like beef, beef heart etc., but you need to feed then very small portions

But note that never feed your baby piranha fish the foods like hamburgers,  bacon, sausages, Turkey and fried or fast foods these may harm your piranha fish health because these foods contain spices and so never feed your fish these kind of foods

Hope this Information is helpful
