Freshwater and tropical fish often benefit from having a varied diet. This might include live freshwater fish food, fish food pellets and some of the best flake food for freshwater aquarium fish.

Depending on the species of fish you keep, you’ll usually be feeding your pets two to three times every day. And depending on the kind of food for freshwater fish you’re giving them, the amount of each feeding will vary. For fish flakes, just a few flakes per fish is usually sufficient. A good rule of thumb is that all food should be consumed within two minutes or less. Be careful not to overfeed your fish, which can lead to the clouding of your aquarium water and may harm the wellbeing of your fish pets. Consult your veterinarian for more information on the best feeding practices for your unique pets’ needs. Check out our Fish Food and Feeding Tips guide for more details. And if you’re concerned about remembering to feed your fish enough or are going on vacation, consider our fish feeding accessories—including automatic and vacation fish feeders.
