Cardinal tetras are carnivorous-leaning omnivores that eat small invertebrates and aquatic plants in nature. In captivity, use artificial fish feed as the staple plus animal feeds like tubifex worms, mealworms, and brine shrimp.
Appropriate live food adds protein and gloss, but clean and disinfect it before feeding.
