The best betta food

Feeding a betta is a small-quantities problem, not a brand problem. Get the amount right and almost any decent pellet works; get it wrong and no food on this page saves you.

We have not used any of this gear. Every pick below is chosen from published manufacturer specifications and the arithmetic on how we pick, which you can re-run yourself.

Feed a betta 2 to 4 small floating pellets, twice a day, and buy the smallest pot of a betta-specific pellet you can find rather than the best-reviewed big one. A betta is a carnivore whose stomach is roughly the size of its eye, so the amount matters far more than the brand: overfeeding is the single most common cause of the bloating, constipation and foul water that new betta keepers ask about. Keep freeze-dried bloodworms as a weekly treat, rehydrated before feeding, and fast the fish one day a week.

This page is short on brand arguments and long on quantities, because that is where the actual risk is. Every food below is competent. The difference between a betta that lives four years and one that dies bloated at eighteen months is almost always feeding volume, temperature and water quality — not which pot you bought.

How much, and how often

  1. 2 to 4 pellets, twice a day. That is the whole feeding schedule. A betta's stomach is about the size of its eye, and pellets swell after they are swallowed.
  2. Everything eaten in under two minutes. If food is still floating after that, you fed too much. Net it out.
  3. One fasting day a week. A day without food lets the gut clear and is a standard, harmless practice in the hobby.
  4. Treats once or twice a week, not daily. Freeze-dried bloodworms or brine shrimp, rehydrated in tank water first so they do not expand inside the fish.
  5. Never feed to the pot's instructions. Food packaging is written by the company selling the food, and a pot sized for a store display is not a portion guide.

How we judged these

  • Floating, and small. A betta feeds at the surface with an upturned mouth. Sinking or oversized food is wasted food and, in the substrate, future ammonia.
  • Carnivore-appropriate. Insect larvae, fish and shrimp meal rather than a grain-first tropical formula.
  • Pot size against one fish. The best food in a pot you cannot finish in six months is a worse purchase than a decent food in a small pot.
  • What the maker actually publishes. Several of these brands' own sites do not respond to us. Where we could not verify a guaranteed analysis, we say so instead of repeating numbers we have not seen.
  • Currently purchasable. Every food here had a live buy box when this page was written.

Storage, which quietly decides food quality

Dry fish food degrades from the moment the seal breaks. Heat, light, air and humidity all accelerate it, and the fats and vitamins go first — which is precisely the part you are buying.

Three habits cover it. Keep the pot closed and out of direct light, away from the heat of the tank hood. Never shake food out over an open tank, because steam gets in and damp food spoils fast. And decant a few weeks' worth into a small container if the pot is large, so most of the food stays sealed.

If a food smells rancid or has clumped, throw it out. A pot of food costs less than a fish.

What food cannot fix

A betta in unheated water eats badly, digests badly and gets ill, whatever it is fed — the temperature comes first, which is why we recommend a heater sized for a 5 gallon tank on any betta tank.

And food is the main input to your nitrogen cycle. Every uneaten pellet becomes ammonia, so overfeeding is simultaneously a health problem and a water-quality one. If a betta tank is cloudy or the fish is listless, start with why is my fish tank water cloudy and a test kit rather than a new food.

Tank mates change the calculation too: food that suits a betta may not suit the fish sharing the tank with it, which is one of several reasons betta tank mates need thinking about before they arrive.

Fluval Bug Bites Betta Formula

Pick 1

Fluval Bug Bites Betta Formula

The everyday staple

The number
Sold as a 1.05 oz pot of granules sized for a betta's mouth. At the 2 to 4 granules twice a day a betta actually eats, a pot this size lasts far longer than the food stays fresh.

Bettas are carnivores, and insect larvae are closer to what a wild betta eats than a grain-based flake is. That is the whole argument for this range, and it is a reasonable one.

The granules are small and they float, which matters: a betta is a surface feeder with an upturned mouth, and food that sinks straight past it ends up rotting in the substrate.

It is also the same family as the tropical formula on our general fish food shortlist, so a community keeper with a betta tank as well can stay in one range.

The honest costs. The pot is bigger than one betta needs — buy the smallest size available and store it sealed and dark. Fluval's own site does not respond to us, so we print no guaranteed analysis. And insect-based food is not magic: overfed, it bloats a fish exactly like any other food.

Hikari Betta Bio-Gold Baby Pellets

Pick 2

Hikari Betta Bio-Gold Baby Pellets

Finishing the pot while it is still fresh

The number
0.088 oz of floating baby pellets. One betta eats a few pellets twice a day, so this pot is measured in months rather than years, which is the point.

Almost every betta food discussion is about brands. It should be about freshness. Fish food is a dry organic product with fats in it, and once opened it degrades — the vitamins first. A pot you finish in a few months is better food than a bigger pot of anything.

This is the smallest pot of a widely stocked betta pellet we could verify in stock, and the pellets themselves are small enough that a betta swallows them without effort.

The honest costs. The per-ounce price is the highest here by a distance, which is the trade for the small pot. Hikari's own site does not respond to us, so no guaranteed analysis is printed. And a small pot means reordering, which is a mild but real annoyance.

Tetra TetraBetta PLUS Floating Mini Pellets

Pick 3

Tetra TetraBetta PLUS Floating Mini Pellets

The cheapest sound staple

The number
A 1.2 oz pot of floating mini pellets, stated to include a natural color enhancer. Same caveat as any large pot for one fish: it will outlast its freshness.

There is nothing wrong with the cheap option here. A betta fed three pellets twice a day of a competent floating pellet lives a full life, and the money saved is better spent on a heater than on a premium pot you throw half of away.

Mini pellets and floating are the two features that matter, and this has both.

The honest costs. Tetra's site does not respond to us, so we can say least about this food's ingredient list — and a color-enhancing claim is a marketing claim, not a nutrition one. The 1.2 oz pot is too big for one fish, so decant a few weeks' worth and keep the rest sealed.

Omega One Betta Combo, Variety Pack of 3

Pick 4

Omega One Betta Combo, Variety Pack of 3

Variety without buying three separate pots

The number
A variety pack of three, combining pellets with freeze-dried items. One purchase covering both the everyday food and the once-a-week treat.

Variety is genuinely useful for a carnivore: a rotation of pellet and freeze-dried food is closer to a real diet than the same pellet every day for four years.

Buying it as a pack removes the main obstacle, which is that a single betta will never get through three full-size pots before they go stale.

The honest costs. It costs several times a single pot, and part of what you are buying is treats rather than staple food — treats are a supplement, not a diet. Omega One's own site fails TLS verification from here, so no guaranteed analysis is printed.

Tetra BloodWorms Freeze-Dried Supplement

Pick 5

Tetra BloodWorms Freeze-Dried Supplement

The weekly treat, and nothing more

Bloodworms are the food a betta will always eat, which is exactly why they cause trouble. They are a treat: high in protein, low in the rest of a diet, and implicated in constipation when fed daily.

Once or twice a week, rehydrated in a spoon of tank water first, they are a genuinely good addition — particularly for a fish that has gone off its pellets.

The honest costs. Freeze-dried food expands after it is swallowed, so feeding it dry is a known route to bloat. It is a supplement sold in a pot large enough to be used as a staple, which is a trap. And a fish that has learned bloodworms exist may refuse pellets for a day or two out of principle.

Published specifications for the Tetra BloodWorms Freeze-Dried Supplement
What it isA single-ingredient freeze-dried invertebrate, sold as a supplement rather than a staple
Maker's own guidanceTetra directs that its Bloodworms be fed in conjunction with a primary food such as TetraMin; retailer guidance is commonly two to three feeds a week alongside a staple diet
What it does not doNo complete guaranteed analysis of the kind the staple foods publish, because it is not sold as a complete diet. Fed as the main food it is an unbalanced diet, and that is the makers' position, not ours.

Tetra TetraMin Plus Tropical Flakes

Not a betta food

The skip entry is not a bad product — it is on our community fish food shortlist for good reason. It is simply not a betta food, and it is what a betta gets fed when there is one tub in the cupboard.

Two problems. Tropical flake is formulated for omnivores, so the protein profile is wrong for an obligate carnivore. And flakes break up and sink, which suits mid-water fish and wastes food on a surface feeder.

If it is all you have on a given evening, a betta will eat it and be fine. As the everyday diet for years, buy a betta pellet instead.

What it does not doFlake goes soggy and sinks once it is wet, so anything not eaten in a couple of minutes becomes waste rather than food. The tub is sized for far more fish than a first tank holds, and an opened tub does not stay fresh indefinitely.

Questions people actually ask

Frequently asked questions

+ How much should I feed a betta?
Two to four small pellets, twice a day, with everything eaten inside two minutes. A betta's stomach is roughly the size of its eye and pellets swell once swallowed, so the portion that looks stingy is the correct one. Fast the fish one day a week.
+ What is the best food for a betta?
A small floating pellet formulated for bettas, bought in the smallest pot you can find. Insect-larvae or fish-and-shrimp based pellets suit a carnivore better than a grain-first tropical flake. The brand matters far less than the quantity you feed and how fresh the pot is.
+ Can bettas eat tropical fish flakes?
They will eat them, and occasionally that is fine, but tropical flake is formulated for omnivores and breaks up and sinks. As a permanent diet for a surface-feeding carnivore it is the wrong food and it wastes more of itself in the substrate.
+ How often should I feed bloodworms to a betta?
Once or twice a week at most, as a treat rather than a meal, and rehydrated in a spoon of tank water first so the freeze-dried worms do not expand inside the fish. Daily bloodworms are a common route to constipation and bloat.
+ Why won't my betta eat?
Check the temperature first: a betta below the mid 70s Fahrenheit goes off its food. Then test the water, because ammonia and nitrite suppress appetite before they produce visible symptoms. A recently moved fish may also refuse food for a few days, and a fish that has been fed bloodworms may hold out for more.
+ Should I fast my betta?
Yes, one day a week is a normal and harmless practice that helps prevent constipation in a fish that is easy to overfeed. A betta that has stopped eating and looks swollen can be fasted for two or three days, with the water tested in the meantime.
