Let’s take a look at our list:

1. TetraColor PLUS Tropical Flakes


  • Improves fish color
  • Great for top feeders
  • Easy to digest
  • High nutritional value


  • Not for bottom feeders

If you are looking for high-quality tropical fish food that will improve your fish’s color, the TetraColor PLUS Tropical Flakes is a great option to consider.

The flakes are created with a specialized tropical formulation that makes them easy to digest and have high nutritional value. You’ll never have to worry about your fish getting sick or lacking any supplements with these power-packed flakes.

Moreover, as they are lightweight flakes, the TetraColor PLUS Tropical Flakes are suitable if you have top feeders or fast fish. That is because the flakes tend to float for longer and are much easier for fish that remain near the top of your tank to eat in time.

Another thing we love about this fish food is that Tetra has used a unique clear water formula to make the flakes very easily digestible. The company claims it is their most digestible fish food ever. Thanks to this, the TetraColor PLUS produces less waste, adding to water clarity over time.

It is suitable for all kinds of fish and age ranges, so you won’t have to worry about selective or isolated feeding mechanisms. Overall, if you want to ensure that your fish stay healthy, agile, and their color stays vibrant for long, we recommend checking out the TetraColor PLUS Tropical Flakes.

  • Not suitable for all fish

The Aqueon Tropical Flakes is an excellent option for high-quality fish food on a tight budget. These fish flakes utilize natural ingredients and contain various important nutrients, so you won’t have to worry about your pet’s health with these.

It means that more of the nutrition gets absorbed by your pets, and fewer waste materials are produced. It also helps keep your tank water clean as fish waste is known to cause cloudy water.

These flakes can float for extended periods without sinking into your tank or breaking apart. So, these flakes are a perfect fish food for tetras or other fish that tire easily by taking their time, gradually picking off food from your tank’s surface.

One thing we did notice about the Aqueon Tropical Flakes is that they are not suitable for all types of fish. For example, if you have fish that feed in the middle of your tank or bottom feeders, these flakes take a bit too long to sink and will lose most of their nutritional value in the process.

However, a great solution to this would be mixing different types of food for your various pets!

Things To Consider While Choosing Fish Food for Your Fish

Here’s a list of things you should consider when looking for fish food:

Food Form

The most important thing about buying fish food is the type/form of the food you are buying. It means what the food consists of, its shape, size, and other things that create its form. For example, fish food is available in various types ranging from lighter flakes to heavy pellets and chunks.

Buying the correct type of food is essential because they all behave differently and are suitable for different kinds of fish. For example, flakes are light in weight and will float on your tank’s surface, making them perfect for smaller fish that can’t digest bigger pellets.

On the other hand, pellets are much heavier and will sink to the bottom of your tank, which is much more suitable for larger fish and bottom feeders. 

So, be sure to go over the various species of fish and pets you have in your tank and purchase the correct types of fish food for their requirements.

Nutritional Value

Fish food is available in many different forms, each having its constitution and nutritional composition. It means that each option will provide your fish with a different set of beneficial nutrients for their growth.

Because of this, when buying a new kind of fish food, be sure to check out what benefits it provides to your fish, especially in terms of vitamins, protein, amino acids, etc.

All these are important in helping keep your fish healthy and will vary depending on your requirements. For example, if you have young fish and are looking for fish food for growth, a highly nutritious option would be beneficial.


An important factor that many beginner aquarists tend to overlook is how easily our fish can digest the fish food. It is crucial because if your fish have trouble eating and digesting the food, it will lead to less nutrition for them and cause them to produce more waste, which will cloud up your tank.

Easily digestible fish food contains high amounts of protein absorbed internally by your pets and reduces waste production. It is especially beneficial if you have a tank with a high bioload. 

Container Shape

Along with the shape and form of the food, the container is also something you should consider when buying a portion of new fish food. This is because you will be putting your food in the tank directly from the container in most instances.

So, try looking for one with pre-built holes or sliders on the top that allow you to quickly drop food into your tank while making sure too much doesn’t fall in.

On the other hand, you can also purchase a standard container or try feeding with some equipment. However, this will cost a little extra money and maybe a hassle to do regularly.


Let’s take a look at some commonly asked questions related to fish foods:

What Is the Best Time To Feed Fish?

What Can I Feed My Fish When I Run out of Fish Food?
