We’ve all heard the saying that you are what you eat. While we’re not walking around looking like dinner plates, it’s easy to recognize that nutrition is important for general health. The same is true for the tropical fish in your aquarium. Fish will eat just about anything, but that doesn’t mean it’s a good choice for their health. They don’t always make wise eating decisions on their own, so you have to do it for them.
It’s simple to choose the best tropical fish foods if you know what you’re looking for. If you just jump in blindly you might end up with something that’s cheap and doesn’t contain the nutrients your tropical fish really need. Not all fish are the same, but much common tropical fish have similar dietary needs with a few species-specific differences. You should check out what your pet store or your favorite online source has to say about the specific fish you own before you make any food decisions.
The bottom line is that you want your fish to be beautiful, active, and healthy. For that to happen, you need to get them to eat the right food on a regular basis. Learn about what fish need and how different foods try to meet those needs so you can get the best tropical fish foods to fit your unique aquarium.
What to Look for in the Best Tropical Fish Foods
When you’re looking at the container of fish food, you’ll need to know a few things before you can make an informed decision. Here are the main things you’ll see that will help you pick out the best tropical fish foods from the rest:
Type of Fish Food
Fish foods come in a variety of shapes, with the most common being flakes, pellets, and whole. Flakes are dry, thin pieces of food that usually float on the top to allow fish to eat from the surface until they get waterlogged and sink down. Pellets are thicker and usually barrel-shaped or circular. They can float on top of the water or sink slowly to the bottom. Whole food is food that’s made from whole-plant or fish matter, such as frozen or live food.
This is the most important part of tropical fish food. Understand your fish to know what kind of nutrients they need most and where those nutrients should be sourced from. Most fish foods derive their nutrients from plant or fish sources. The best tropical fish foods generally have a mix of plant, bug, and, fish nutrients from high-quality, potent sources. Protein should always be the main nutrient in the mix.
Fish need food that’s appropriately sized for them. Smaller fish need small food while larger fish need larger food. If you give small food to a large fish, they may not be enticed to eat it or they won’t be filled by it, if they even see it at all. Small fish cannot eat large food, and may injure their intestines if forced to eat food too large for them. For multiple sizes of fish, get different foods to suit them all instead of trying get them to eat the same size.
5 Best Tropical Fish Food Options
1. Fluval Bug Bites for Tropical Fish
You can get this Fluval fish food formula with small or medium-large pellets to help accommodate the size of your fish. The container has 1.6oz. of fish food pellets.

Protein is largely derived from black soldier fly larvae and whole salmon. There is a minimum of 40% crude protein to fit the dietary needs of most tropical fish species. The black soldier fly larvae used are bred in smaller batches that help ensure a high-quality protein source in every container of food. No artificial colorants or flavors are added. Fluval claims that the food is naturally easy to digest and palatable for most fish.
- Great for bettas, fry, and very small varieties of fish
- Works well as supplementary food for a frozen food diet or for tiny fish
- Full of natural, healthy ingredients for your fish
- Soft enough to be eaten comfortably by most tropical fish

2. Hikari Tropical Semi-Floating Micro Pellets
These are small packets of micro-granules that come as either a 1 or 2 pack of 0.77oz. packages. The granules are roughly shaped instead of having rounded edges, which makes them easier for fish to grab hold of and eat quickly. They are generally semi-floating, meaning they are suitable for most fish as they can be eaten from the top or as they slowly sink to the bottom. The granules will float for a decent amount of time on top of the water to allow surface eaters to get their fill. Here is where you can find the Hikari Tropical Semi-Floating Micro Pellets.
The nutrient mixture in the food is fish meal and krill meal as the primary sources of protein, with cuttlefish meal and various algae and seaweed also providing extra protein. It has a crude protein minimum of 43%, with many essential vitamins and nutrients being mixed in as well. Artificial flavorings and colorants have been added to help your fish enjoy the food more and to bring out their color.

- Easily digestible and easy for fish to eat
- No need to soak food before putting it in the tank
- Leaves virtually no mess in the water and will not cloud up badly if left at the bottom

Important Factors to Consider
What else do you need to know about fish food? There’s a lot to think about, but the most important parts include:
Types of fish foods
Fish food can be made from almost anything. You can even drop fresh salad greens in your tank to add a little more nutrition to their diets. But, the type of food does matter. Things that are closer to a fish’s natural diet will be easier to digest and are more likely to provide the nutrients they need.
Look for fish-based or bug-based protein sources and plant-based nutrients. While you can find fat and protein sourced from beef and other mammals, it’s not highly recommended as part of the regular diet because it’s more difficult to digest and could cause bloat.
Reliable, trusted brands that have been in the fish business for years are a good choice if you have any doubt about what to buy. They’ve usually been working for a while to perfect their fish food formulas, leading to a lot of solid options that will provide the nutrition your fish need. Also, the larger brands tend to be more economical, even when using high-quality ingredients.
Live, frozen, or dried?
There’s an ongoing debate on whether dried is better than frozen fish food. While frozen food is good in theory, it can have a higher water content than dried food. This means it won’t be as nutrient-dense, making it a bad choice for the core part of a healthy diet. Frozen food is fine as a percentage of a regular diet, but sticking to dried food for the main part is better nutrient-wise.
Live food is a good option, however, the only problem with live food is the possibility of a disease or parasite being transmitted through the food itself.
Many trace nutrients are added to fish foods to beef up their nutrition. Don’t get too excited about most of these. Pay attention to the first three ingredients on the list. They need to be three strong protein sources (plant or animal-based), or else the food may not be giving enough protein for your fish. Protein should make up most of the mix, with other ingredients trailing behind it and a minimum of filler ingredients.
Frequently Asked Questions
How many times a day should you feed tropical fish?
You can feed your fish as many times a day as you want to. Feed them at least once daily, but it’s better if you can feed them in 2 or 3 mini-sessions throughout the day to better simulate their natural eating habits.
How long can fish survive without food?
Most tropical fish can survive up to a week without food, although it’s not recommended to keep them from eating for more than 4 days unless you have to. Tropical fish can easily go 1 or 2 days without food, so don’t worry if you forget to feed them one day or you run out of food a few days before your next container comes in.
How much food do you need to feed your fish?
Only feed your fish as much as they can eat completely within 2 minutes. When in doubt, it’s better to underfeed than to overfeed. If there’s uneaten food, make sure to remove it with a net. Excess food will make the tank dirty (visually and biologically), lower the water quality, and can cause uncomfortable build-up in your fish’s intestines.
It’s a little daunting looking at a long list of different fish foods when you’re not sure what separates one from the other or where to begin for your own fish load. I recommend starting with No products found. for tropical fish because it’s great high-protein food from a good source that works well for most fish.
