Top 10 Fish Food Review & Compared 2020. 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!

1. Tetra Min Tropical Flakes Fish Food

It comes in several sizes, so you can take your pick. As the name says, this is best for tropical freshwater fish. The TetraMin also contains the patented ProCare blend: Omega-3 fatty acid so that your fish gets healthy fat and they can grow bigger and have more energy, various ingredients that boost their immune system, and biotin to improve their metabolism.

2. New Life Spectrum Thera-A Medium 2mm Fish Food

You’re better off buying the 500 gram container, the 250 gram container is too expensive. There are also other pellet sizes aside from 2mm. 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 for the 500-gram container is a bargain.
  • It’s loved by many types of fish, including lyretail and fancy guppies, bala sharks, African cichlids, featherfin and angelicus catfish, emerald and panda coris, weather and clown loaches, and several types of gourami. Even the ghost shrimp and the fiddler crabs can’t get enough of it.
  • It comes with a clearly marked 2 year expiration date.


  • There are only two size options.

3. Hikari Tropical Semi-Floating Micro Pellets Fish Food

These come in different colors denoting different ingredients. Red means it contains protein and amino acids, yellow means vitamins and minerals, and green is vegetable fiber. It’s supposed to be semi-floating, for surface and mid-water feeders.

This is designed for small-mouth tropical fish like tetras and barbs. Owners of cardinals, fancy guppies, and shrimp say their pets love them too.


  • Different nutrients are offered so that the fish gets a balanced diet.
  • Quite a few fish love it.


  • It’s not quite as semi-floating as it ought to be. It may float on the surface for a while, but it won’t sink slowly for the mid-water feeders to enjoy. Instead, it gets to the bottom rather quickly.

4. Tetra Veggie Algae Wafers Fish Food

This is a sinking wafer for tropical bottom feeders, and they contain vegetable nutrients as well as the ProCare blend. The pouch bag can stand up, and is resealable too. These are meant for herbivore fishes, such as goldfish, plecostomus, and corydoras catfish.

It’s great for African Cichlids, goldfish, Swordtails, Platies, Guppies, Mollies, Saltwater Angels and Tangs. For some reason the 2-ounce container costs almost the same as the 4-ounce!


  • The vast majority of owners who’ve tried it report that their fish loved it.
  • 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 Fish Food

 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.


  • Those who have reported that their fish loved it include owners of African cichlids, pleco, catfish, clown loaches, shrimp, and snails.
  • They also report having healthy fish, too.


  • Just be careful where you buy them, because some sellers may offer bad samples.

7. Tetra Cichlid Flakes Fish Food

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.

This particular cichlids dish it’s enhanced with vitamin C and the ProCare blend. Its nutrients help boost the immune system of the fish so they’re more resistant to disease. Also, these flakes remain firm even when fish strike at them. They won’t disintegrate.


  • The price is more reasonable when you get the large 1.75-pound size. That’s because at that price it’s just a couple ¢ per gram, unlike the smallest size that costs much more.
  • These flakes are large, and they’ll stay intact even when fish strike at them.


  • 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 Fish Food

This is freeze-dried blood worms, which makes this the equivalent of prime 5-star rated restaurant steak while its competitors are fast food. This Bio-Pure is as close to being fresh food without actually being fresh food. So it really is a special treat.

  • It is packed with nutrients.
  • ​It’s the cleanest freeze dried food you can buy, prepared with pharmaceutical-grade freeze-drying techniques.
  • It doesn’t cloud the water.
  • The container comes with a nice dispenser top.


  • It’s really expensive, so it’s not exactly realistic to serve this on a daily basis.
  • Freeze-dried food is dry, so they take the time to sink. If you want your bottom feeders to get a taste after the top feeders have had their share, you need to use tongs to bring it to them. You’ll also need to soak them first for a while in the aquarium water so that they’re easier to swallow.

  • For freeze-dried food, the price is remarkably affordable on a per gram basis.
  • It can really brighten the color of the fish.

10. San Francisco Bay Brand Freeze Dried Brine Shrimp Fish Food
