The short answer
For a granule Fluval says contains “up to 40%” black soldier fly larvae, Fluval Bug Bites Tropical Micro Granules; for a flake Tetra calls a “staple food” for top- and mid-feeding fish, TetraMin Tropical Flakes; for a pellet that sinks, per its maker, API Tropical Pellets.
Our verdict
Our Top Picks at a Glance
Nine flake, granule, crisp and pellet foods for tropical community fish, compared on maker pages, Amazon listings and owner reports; we have not tested them. Each is sold and shipped by Amazon.com. Hikari Micro Pellets (an aquatic vet’s tropical pick) and the Omega One, New Life Spectrum, Northfin and Xtreme foods named in owner threads did not pass that seller check.

Before You Buy: Flake or Pellet, Floating or Sinking, First Ingredients
Flake or pellet. Dr. Jessie Sanders, a board-certified fish veterinarian, writes on her practice’s blog (2018, with affiliate links): “If a pellet fits into your fish’s mouth, go with the pellet,” because flakes lose water-soluble vitamins faster. Her own tropical pick, Hikari Micro Pellets, failed our seller check (not sold and shipped by Amazon.com).
Floating or sinking. Per the makers: TetraMin suits “top- and mid-feeding” fish; Aqueon’s flakes float “for surface feeding”; TetraPro crisps “float longer”; Fluval’s granules are “slow sinking”; API’s pellets and Aqueon’s granules sink.
First ingredients (makers’ lists; Amazon listings for API, Aqueon and TetraPro): black soldier fly larvae for all three Fluval foods; fish meal for API Tropical Flakes, both Aqueon foods and TetraPro; whole wheat for API Tropical Pellets; none found for TetraMin.
Freshness. The same vet gives her own rule for opened containers, whatever the printed date: “you have 6 months to feed that food, then toss it”. It is her rule, not a maker’s.
Food is not a treatment: if fish stop eating or look unwell, test the water (our freshwater test kit roundup compares kits; our high ammonia guide covers the usual causes) and contact an aquatic veterinarian.

Detailed Reviews: The 9 Tropical Fish Foods
Fluval Bug Bites Tropical Micro Granules, Insect-first, small fish
1.6 oz · Slow-sinking granules
Keepers of small to medium fish, the size Fluval's listing names, who want insect protein.
$6.99 from AmazonAs of Nov 4, 10:06 UTCVerdict
Slow-sinking granules Fluval says contain “up to 40%” black soldier fly larvae, the first ingredient.
Evidence: No independent test; owner reports. r/Aquariums: Bug Bites Tropical formula for small fish, pack size not stated.
Fluval gives 0.25-1.4 mm, crude protein (min) 40.0% and crude fat (min) 12.5%; the Amazon listing says “0.7–1 mm”. In an r/Aquariums thread, a keeper who switched to “fluval bug bites tropical formula for small fish” felt the rummynose tetras weren’t “able to eat it very well” and ground it smaller. In a second thread, where several replies name Bug Bites, one owner asked whether “the 12.5% min fat” concerns anyone.
Specs (linked: 1.6 oz / 45 g)
- First ingredients: black soldier fly larvae, salmon, fish protein concentrate
Pros
- Insect larvae listed as the first ingredient
Cons
- One owner of a Bug Bites “tropical formula for small fish” (pack not stated) felt rummynose tetras could not eat it well
- Crude fat (min) 12.5%, which another owner questioned
Who should buy it
Keepers of small to medium fish, the size Fluval’s listing names, who want insect protein.
TetraMin Tropical Flakes, Staple flake
Keepers of top- and mid-feeding tropical fish who want a flake Tetra calls a staple food.
$7.97 from AmazonAs of Nov 4, 10:06 UTCVerdict
Flakes Tetra sells “as staple food for your top- and mid-feeding tropical fish”.
Evidence: No independent test; maker specs. Source: TetraMin Tropical Flakes page.
Tetra says the flakes “do not leach color” and won’t cloud water “when used as directed”. The Amazon listing gives no ingredients (“See Label”). Owner mentions of TetraMin in the threads we read are few; in the r/Aquariums brand thread, a former fish-store worker answered “Not Tetra/Tetramin”, naming Omega One as the store’s go-to.
Specs (linked: 2.2 oz)
- First ingredients: not published in the text we read
Pros
- Won’t cloud water “when used as directed”, per Tetra
Cons
- No ingredient list in the text we read
Who should buy it
Keepers of top- and mid-feeding tropical fish who want a flake Tetra calls a staple food.
API Tropical Pellets, Sinking pellet
Verdict
Sinking pellets API says are “ideal for tropical community fish including Angelfish, Tetras, Barbs and Discus”.
Evidence: No independent test; maker specs. Source: API Tropical Pellets page and Amazon listing.
API says “each pellet contains nutritionally-enhanced proteins to promote optimal digestion and produce overall less ammonia” (no figure or comparison on the page). API lists one size, 4.2 oz.
Specs (linked: 4.2 oz)
- First ingredients: whole wheat, whole menhaden fish meal, squid meal (listing)
Pros
- A sinking pellet for fish that feed below the surface
Cons
- Lists whole wheat first, ahead of fish meal (listing)
Fluval Bug Bites Tropical Granules, Insect-first, larger fish
1.6 oz · Slow-sinking granules
Keepers of medium to large tropical fish.
$5.99 from AmazonAs of Nov 4, 10:06 UTCVerdict
The larger-granule sibling of #1, with the same ingredient list; Fluval gives 1.4-2.0 mm.
Evidence: No independent test; maker specs. Source: Fluval Bug Bites Tropical Granules page.
Amazon sells it on #1’s listing as “Large Granules”, and its bullets say “1.4-1.6mm”. An r/Aquariums owner who feeds Bug Bites granules (size not stated) wrote “Fish really love the bug bites but it’s a little hard.”
Specs (linked: 1.6 oz / 45 g)
- First ingredients: black soldier fly larvae, salmon, fish protein concentrate
Pros
- Insect larvae first, in a granule sized for bigger mouths
Cons
- Fluval’s listing aims it at medium to large fish, not small ones
- Same 12.5% crude fat minimum as #1
Fluval Bug Bites Color Enhancing Flakes, Insect-first flake
Verdict
Flakes Fluval says contain “46% crude protein from multiple quality sources”, with black soldier fly larvae first.
Evidence: No independent test; maker specs. Source: Fluval Bug Bites Color Enhancing Flakes page.
Fluval gives crude fat (min) 7%, against 12.5% for its granules. The Amazon bullets repeat the granule wording (“whole salmon”); Fluval’s list has herring meal second and salmon oil, not whole salmon. Aquarium Store Depot links this pack and calls it “great for variety and smaller fish”.
Specs (linked: 3.17 oz / 90 g)
- First ingredients: dried black soldier fly larvae, herring meal, wheat flour
Pros
- Insect larvae first, in a flake with a lower fat minimum
Cons
- A flake: the affiliate blog Aquarium Store Depot says Fluval’s “pellet product is the better buy if you have to choose one” (product not named)
API Tropical Flakes, Flake, ammonia claim
Verdict
Flakes for which API says “API Fish Food contains nutritionally-enhanced protein for maximum digestion and produce up to 30% less ammonia” (comparison not stated).
Evidence: No independent test; maker specs. Source: API Tropical Flakes page and Amazon listing.
API calls it “ideal for all types of tropical fish including Tetras, Angelfish, Discus, Barbs and Guppies”. Unlike TetraMin, its ingredient list is published in the text we read (on the listing) and API gives an ammonia figure. It is a different food from the API Betta Flakes in our betta guide.
Specs (linked: 1.1 oz)
- First ingredients: whole menhaden fish meal, whole wheat, squid meal (listing)
Pros
- Lists whole menhaden fish meal first (listing)
Cons
- Ingredient list given only on the Amazon listing
Aqueon Tropical Flakes, Floating flake, species list
Verdict
Floating flakes Aqueon lists as “Ideal for Angelfish, Tetra Species, Barb Species, Rasboras, Danios” and more.
Evidence: No independent test; maker specs. Source: Aqueon Tropical Flakes page and Amazon listing.
Aqueon says they are “formulated so that fish utilize more of what they eat and create less waste” and will not cloud water “when fed as directed”. Unlike TetraMin, Aqueon names the species and publishes ingredients in the text we read (on the listing).
Specs (linked: 3.59 oz)
- First ingredients: whole fish meal, wheat flour, dehulled soybean meal (listing)
Pros
- Aqueon names the community species it is made for
Cons
- The listing’s direction gives a time limit but no number of feedings a day
Aqueon Tropical Granules, Sinking granules
Keepers of larger fish, which Aqueon says often prefer granules.
$5.29 from AmazonAs of Nov 4, 10:06 UTCVerdict
Granules Aqueon says “sink to the bottom of the aquarium more quickly than flakes and are often preferred for larger fish”.
Evidence: No independent test; maker specs. Source: Aqueon Tropical Granules page and Amazon listing.
Aqueon lists the same species as for its flakes, from angelfish to Corydoras catfish.
Specs (linked: 6.5 oz)
- First ingredients: whole fish meal, wheat flour, dehulled soybean meal (listing)
Pros
- Sinks faster than flakes, per Aqueon
Cons
- Aqueon says granules are “often preferred for larger fish”
TetraPro Tropical Crisps, Crisps
Verdict
Crisps Tetra says its diet “feeds cleaner than ordinary flakes” and that the crisps “float longer to allow fish more time to eat”.
Evidence: No independent test; maker specs. Source: TetraPro Tropical Crisps page.
Tetra’s Amazon listing adds that the crisps “leave up to 35 percent less waste behind than competing flakes” (basis not stated).
Specs (linked: 6.70 oz)
- First ingredients: fish meal, dried yeast, corn starch (listing)
Pros
- Crisps that float longer than flakes, per Tetra
Cons
- The highest pack price here, for the largest pack
How Much and How Often to Feed Tropical Fish
Follow the label of the food you buy; the makers’ directions differ (maker page unless noted):
| Food | Maker’s direction (quoted) |
|---|---|
| Fluval Bug Bites (#1, #4, #5) | “Feed as much as fish can eat in two minutes, two or three times daily.” |
| TetraMin flakes | “Feed two to three times daily, only as much as your fish can consume within three minutes.” |
| API Tropical Flakes, Pellets | “Feed twice a day, only as much as fish will consume within 3 minutes.” |
| Aqueon Tropical Flakes, Granules | “Feed no more than what the fish can eat within 1 – 2 minutes.” (listing; no daily number given) |
| TetraPro crisps | “Feed two to three times daily, only as much as your fish can consume within three minutes.” (listing) |
API says unconsumed or poorly digested food “causes waste and raises ammonia levels”; if the water turns cloudy, see why aquarium water turns cloudy. Going away? See how to feed fish while on vacation.
Frequently Asked Questions
Q. Which is better for tropical fish, flakes or pellets?
The vet above prefers a pellet that fits the fish’s mouth. One r/Aquariums owner mixes “fluval bug bites pellets and their flakes”.
Q. Should I feed my tropical fish every day?
Fluval, Tetra and API give daily directions (see the table above): twice a day for API, two or three times for Fluval and Tetra. Aqueon’s listing gives only a time limit. Follow the label of the food you use.
Q. What is the best brand of tropical fish food?
No independent test names one. Fluval Bug Bites, Hikari, Omega One and New Life Spectrum come up most in the threads we read; of those, only Fluval passed our seller check. API and Aqueon were not named in those threads.
