What Can Fish Eat?

Vet-reviewed food safety guides for fish

Feeding pet fish the wrong foods — or overfeeding — can quickly degrade water quality, cause disease, or kill your fish. Different species have very different dietary needs: betta fish are carnivorous while goldfish are omnivores. Our guides cover safe foods, correct portion sizes, and feeding frequency for the most popular pet fish species. We also cover which human foods are safe to offer as treats and which to avoid completely to keep your fish healthy and your tank water clean.
