If you want your fish to enjoy living in the aquarium and thrive then you need to give them the best fish food you can afford. This is basic biology (and common sense), and it’s perhaps one of the first things people learn about keeping any sort of pet (except if you have a pet rock, but then that’s a different thing entirely!).
So it’s crucial that you make sure you’re feeding your fish properly and that means researching through Google and visiting forums that have members who also own the same fish species you have.
There are lots of very popular fish you can keep, and their popularity means that you get lots of information regarding their preferences for food and environment.
What to Look For in Good Fish Food?
There are several factors you need to consider when you’re trying to determine the right fish food for your fish. You’ll need to consider the size of the pellets because it has to be right for the fish's mouth.
You also need to consider how quickly the food falls to the bottom. Some food types float, which is perfect for some surface-feeding fish. Others sink slowly so that they can feed the mid-water feeders. Others sink quickly for the bottom feeders.
You may also want to check the hardness of the food. For example, freeze-dried food may be difficult to swallow without being soaked in water first. Then you also want to see if it disintegrates quickly because that would be a waste of food and it would just contaminate the water.
And of course, you also need to factor in the nutrient requirements of the fish. Some fish feed on vegetables, while others may need a high protein diet. You may even want to find out if a certain food results in more waste products.
If you’re a newbie, you better stick to freshwater fish first because they’re easier to handle, before you start with saltwater tanks.
Whatever you get, you better know what kind of fish food brand to buy. You can’t just buy the cheapest fish food pellets when your fish specifically needs tropical fish food.

New Life Spectrum (NLS) is also highly regarded in the industry, and their products contain garlic with lots of anti-parasitic ingredients.
Many fish owners admit to only using this product (along with frozen food) to feed their fish.

- The price is more than reasonable, especially when you consider that it lasts for quite a long while.
- The flakes are large, and while that may be fine for some fish it may be too big for others.
6. Omega One Veggie Rounds
An 8.1-ounce container is rather odd, and it doesn’t make much sense when it’s in grams (230g) either. In any case, have a look at the price.
As these are veggie fish food, these are for herbivores but they can be for salt and freshwater fish. They’re made with spirulina (which seems a popular ingredient) and fresh kelp.
The manufacturer, Omega One, is actually one of just two companies in Alaska licensed to harvest fresh kelp along the southeast Alaskan shoreline. So they have stores of fresh kelp in stock, which explains why this food seem to have a deeper green color than another veggie (or kelp) products.
This food is simply packed with nutrients, and Omega One has no reason to skimp on the ingredients.

7. TetraCichlid Cichlid Flakes
Once again we’re back to the reliable Tetra brand, and this time the food is for top and mid-water feeders.
The 1.75-pound container (roughly 794 grams) is cheap, although you can first try the smallest 1.58-ounce (almost 45-gram) size to see if your fish takes the food.

- However, if you do get the large container, that’s going to take forever to finish off!
8. Hikari Bio-Pure Freeze Dried Blood Worms

Types of Fish Food
So what kind of fish food can you get? Actually, there are quite a few options. That’s understandable, since there lots of fish species you can keep, and some fish may not thrive with just the same food every time. (It’s probably like eating the world’s most incredible pizza—after a week of eating just that, even you’d rebel).
The first type is dry fish food, and there are several varieties:
- Flakes: fish flake food is probably the most common option of them all, as pretty much all the common types of aquarium fish will go for it.
- Crisps: these crisps tend to float for a long period of time. So it’s more likely that the fish will get them before they fall uneaten to the bottom. They also tend to create less waste. These crisps are ideal for small to medium-sized fish.
- Granules: these also tend to sink very slowly to the ground, so it’s available to all the fish in the tank. They also come in bite-sized pieces to make them easier to consume.
- Tablets: these sink very quickly, so they’re ideal for the bottom-feeders like loaches and catfish.
- Wafers: these also sink quickly, but they’re a bit larger.
- Sticks: larger fish go for this type of food.
- Pellets: these float and you can get tiny ones for your bettas. There are also larger pellets for larger fish.
- Supplements and treats: these complement the main diet of the fish.
Some types of fish food are designed as blocks, which are meant to be placed inside the aquarium to feed the fish for days on end. The blocks release just small amounts as they dissolve, so the fish can be fed for several days while the owner is on vacation.
Some fish food types are frozen or freeze dried which may be necessary to preserve the protein and other nutrients. Then there are medicated fish food servings that deliver medication to the fish, without contaminating the water and environment like a bath treatment would do.
And of course, you can also serve your fish earthworms from your garden or any live food.
Drawbacks to Buying Online
Many newbies don’t like buying fish food online because they have to wait for the delivery and sometimes shipping comes with a fee as well. And you can’t get live food online.
It can also be confusing to be confronted with so many options and so many reviews. Some beginners just consult their local pet store and get food recommendations from the seller. That makes everything faster and less confusing
Advantages of Buying Online
But there are advantages to buying online too.
One main advantage is that online you can just about find any type of fish food except for live food. You’re not limited to what your local seller has in stock. You can buy any type of food including freeze-dried fish food or flakes, and it can be any size available.
And what’s more, you’re also not limited to a single person’s recommendations. When you’re online, reviews are pretty much easily available on seller sites like Amazon. You’ll know what other owners have gone through so you know what to expect. You’ll know how many owners report that their fish liked it, and you’ll also find out just how often it’s been ignored by the fish.
In some cases, you can get discounts when you buy online when you buy in bulk. So that means you won’t have to pay as much.
Your best bet, if you’re looking online, is to read reviews so that you can get the comments of other customers who have the same fish as you do. It’s also a good idea to pick the food designed specifically for your fish. So if a fish food is branded as ideal for goldfish, then as a goldfish owner you can have it as one of your options.
