Here we have some more fairly basic yet high quality fish flakes. Because these are flakes, they also float in the water column. They don’t sink too quickly, therefore making them ideal for relatively slow moving fish that need a certain amount of time to eat out of the middle of the water column. With that being said, they should be suitable for most types of fish.

This particular product is designed for all sorts of freshwater and saltwater fish that have similar nutritional requirements.

3. Omega One Betta Combo

Here we have a fantastic combination of different foods all designed specifically for betta fish. What you get here are three specific products, one that is a flake food, a pellet food, and blood worms for treats.

We personally really like these products, because the flakes float in the water, therefore making them ideal for fish that like to eat their food at the top or in the middle of the water column. The pellets and then are of the sinking variety, which means that they are better for fish that like to eat their food in the bottom of the aquarium.

Both the pellets and the flakes are specifically designed for freshwater tropical fish, which means that they contain a balance of nutrients, including proteins, fatty acids, beta carotenes, and other great ingredients that are all designed to help promote the healthy function of all fish.

Just keep in mind that this food is specifically designed for betta fish, so you may not want to give it to other types, although similar tropical fish could probably eat it as well.

What we really like here is that all of the proteins here are raw and unprocessed, which means that they are easily absorbed by your fish. The fact that you get a container of blood worms included here, which is a great high protein treat, is just an added bonus.


  • 3 for 1  – great deal
  • Nutritionally balanced
  • Ideal for betta fish
  • Natural, safe, and high-quality


  • Specifically for betta fish

If you have a betta fish, and you want to feed them a variety of foods, then this is by far the best product considered.

Fish Food for Aquariums Buyers Guide: What to Look Out For

Before you go out and buy any old fish food, here are a few important things you need to look out for.

Type of Fish

Different fish have different dietary requirements, and you need to account for this. If the food in question says that it’s designed for goldfish, don’t try and give it to your cichlids. Fish foods are relatively specific to the species.

Quality Ingredients

It is also very important that you provide your fish with fish foods that have quality ingredients. Although it’s not the worst thing, things like fish meal are best avoided in most cases, although they can serve specific purposes. What it comes down to is that the ingredients listed on the package should be ones that you can easily pronounce and recognize.

Floating vs Sinking

Remember that there are both floating and sinking foods, mainly flakes and pellets. Always do some research in terms of the fish you have and what type of food they would prefer. Slower fish tend to prefer floating foods, whereas faster fish are generally fine with sinking foods. There are however also other considerations to keep in mind here.
