10 Best Flake Fish Foods 2021 – Reviews & Top Picks

Nicole Cosgrove

May 3, 2021

Aquarium fish are beautiful, inexpensive pets that are relatively easy to care for. While some types of fish have specific dietary requirements, others can eat good quality general fish food. Of the different types of fish food that exist, fish flakes are the most common. They are suitable for surface feeders and those that prefer to feed in the middle of the tank. In fact, by the time the flakes reach the bottom of the tank, they have lost most of their nutrients.

Their popularity and convenience mean that there are many brands and specific types of fish flakes available, including flakes that are suitable for all fish and those for specific species. There are also flakes that aim to improve the color of your fish, which can further enhance the natural beauty of your aquarium stock.

With such a wide range of fish flakes on the market, and their varied purpose, it is important that you choose the right one. That’s why we’ve looked at dozens of different varieties to choose the ten best. We’ve compiled reviews and listed the benefits and uses of each, so that you can choose the food that best suits you and your fish.

  • The 10 Best Flake Fish Foods – Reviews 2021

    1. TetraMin Tropical Flakes Fish Food – Best Overall

    TetraMin Tropical Flakes Fish Food

    TetraMin tropical flakes are freshwater flakes made with fish meal, yeast, and brown rice. They are easy to digest and don’t discolor the water, so you won’t have to increase your water cleaning regimen. They have high levels of protein and fat, as well as a varied selection of vitamins and minerals chosen to prevent disease and keep your fish as healthy as possible, while the Omega-3 maintains a healthy immune system to protect against disease.

    The tropical flakes have proven very popular with owners and have a high acceptance rate with fish, so you should have no problems getting your tropical stock to eat them. The only minor complaint about this food is that it is priced higher than some of the others in this list, but you do get what you pay for. In this case, you get high-quality, appealing food that enables your fish to thrive without requiring extra tank care or water cleaning.

    Pros
    • High in protein and fat
    • Doesn’t discolor tank water
    • Vitamins and Omega-3 protect against disease
    • Popular with owners and their fish
    Cons
    • Maybe a little pricey

    2. Wardley Flake Tropical Fish Food – Best Value

    Wardley Flake Tropical Fish Food

    Wardley’s tropical fish food flakes are inexpensive, help ensure the good health of your fish, and most users report that they do not discolor or cloud the tank water. In our tests, we found these to be the best flake fish food for the money. They have been formulated with a high protein-to-fat ratio which encourages growth from all fish, and the ingredients do not incorporate any artificial colors so your water should remain clear. Artificial colorings can leech into the water, which not only ruins the aesthetics of your tank, but it means more frequent water changes that can stress your fish, as well as you.

    Wardley claims that these are large fish flakes and most buyers agree. However, there has been a small number of owners reporting that the flakes have crumbled during shipping, leaving dust that can’t be fed to their fish. There have been a small number of people complaining that the flakes leave a cloud in the water, but this could be due to the dust or because of overfeeding.

    Pros
    • Good value for money
    • Mostly large flakes
    • No artificial colouring
    • High protein-to-fat ratio to encourage fish growth
    Cons
    • Some reports of crumbled flakes
    • Small number of users reported cloudy water

    3. Omega One Betta Buffet Flakes Fish Food – Premium Choice

    Omega One Betta Buffet Flakes Fish Food

    Betta Buffet flakes from Omega One have a high protein level that is especially useful for betta fish, which demand a high-protein diet. This ratio also means that the flakes are less likely to dissolve in water, which means that the food will not cloud or discolor the water and will leave a healthier living environment for your bettas. This also means that you won’t have to increase your water changes or cleaning requirements.

    Ingredients include wild salmon, and the food has been formulated with less starch and filler. This is a premium fish food, which means that you may have to pay extra, but if you want healthy bettas with vibrant colors and a strong immune system built up by the Omega-3 and Omega-6, this is a very good choice of food that receives high ratings from buyers and betta owners.

    Although billed as ideal for betta, this is a tropical fish flake that can be safely fed to other fish, so it can be used in a tank with mixed fish stock. The major drawback of this product is that it is only available in smaller bottles and at a premium price, so it does end up costing a lot more than other foods.

    Pros
    • Popular with betta fish
    • High protein ideal for betta
    • No clouding or water discoloration
    • Salmon skin enhances fish color
    Cons

    divider-fishConclusion

    Finding and feeding a good fish food is imperative to the good health and upkeep of your freshwater fish. Good food not only ensures a balanced diet, but it can enhance the colors and even improve your fish’s immune system. Choose according to the species of fish you have, as well as their size, and the combination of species you have in your tank. Remember that some fish are surface feeders and others are bottom feeders and provide food to meet the needs of the individuals as well as the group.

    While compiling our reviews we found that the TetraMin tropical fish flakes are the best food, providing a balanced diet at a good price. Wardley flake tropical fish food is the best fish flakes for the money, costing less than the TetraMin and enjoying almost as many positive reviews.

    An aquarium is a great addition to any home, and fish make relaxing and enjoyable pets, but you do need to ensure that they are well fed and receive the required vitamins and nutrients. We hope that our reviews help you find the best food for your fish so that you can continue enjoying them at their best.
