9 Best Sinking Fish Foods – Reviews & Top Picks

Because they spend most of their time on the surface of the water, some fish require food that will not sink to the aquarium floor.

Fish that eat at the bottom of the tank are called bottom eaters. This requires using fish food that can sink to the bottom to feed them.

It can be difficult to find high-quality sink food for your fish in the multitude of options available. As luck would have it, BestForPets (bestforpets.org) has investigated this for you.

In this article, we'll take a look at some of the best sinking fish foods available today.

An Instructional Manual for Shoppers

Your fish may not be able to eat just anything. Do your research on the labels and stick to known brands to ensure you get the best quality and nutrients.

Fish Food and Its Nutritional Value

Fish, like their terrestrial counterparts, come in a variety of diet types, including carnivore, herbivore, and omnivore (eats both plants and animals).

So, their dietary requirements will be different. Predatory fish like carnivores require a diet rich in animal protein (between 50 and 70 percent ). Make sure there is some fat and fiber in the food as well so that they have a well-rounded diet.

Due to their varied diets, omnivore fish don’t need as high of a protein content as their carnivorous counterparts. Protein should make up 30-40% of an omnivore fish’s diet, fat should make up 2%-5%, and fiber should make up 3-8%.

The protein quality of their meal is still important, even if herbivores exclusively consume plants and vegetables.


When it comes to food, bottom feeders are the fish you want to catch. They will continue to exhibit the same behavior even when kept in an aquarium. You will need to choose a sink food that meets the nutritional requirements of the fish. So BestForPets (bestforpets.org) has come up with a list of the best sinking fish foods.

When deciding what to buy, keep in mind that Tetra Tetramin Large Flakes are a high-quality, nutrient-rich product that can be used to provide a balanced diet for underfeeders. Wardley shrimp pellets are the best value for high-quality sink food if you’re on a tight budget.


The Highest Quality Tetra Tetramin Large Flakes

Tetramin Large Flakes, made by Tetra, are the best sinking fish food you can buy since they provide a complete and balanced diet for your bottom feeder. They have added vitamins, minerals, and other nutrients that are vital to your fish’s well-being.

The macronutrient breakdown of this dish is as follows: 47% protein, 3% fiber, 1% phosphate, and 6% water. It also contains biotin and omega-3, which will increase your fish’s energy and metabolism.

The flakes are simple for the animal’s digestive system to process, thus reducing waste production. As a result, the aquarium’s water will maintain its purity for a longer period of time.

Tetramin Flakes are safe for all fish species and have been shown to improve overall health and immunity.

The only negative aspect of these flakes is that they disintegrate quite quickly. That they won’t be sticking around for very long at all. Even so, if you feed your fish the right way, you won’t have to worry about them wasting any time in devouring the flakes as they sink to the bottom.

Given all these advantages, it’s easy to understand why we’ve settled on this product as our top pick.


  • Enhanced with vitamins and minerals for superior nourishment
  • Excellent for a wide variety of fish.
  • Does not make water unusable
  • Offers a range of sizes


  • Is easily dissolved


Value for Money: Wardley Shrimp Pellets

Several researchers collaborated to create this sinking fish meal, as they sought to identify the optimal diet for bottom feeders.

Shrimp pellets from Wardley drop rapidly to the bottom, which is the first thing you’ll notice about them. By doing so, the top feeders are protected from eating food that is not intended for them. Moreover, the pellets’ high protein content makes them a good choice for bottom feeders, as this is an essential nutrient for the majority of these fish.

The vitamin C content in Wardley Shrimp Pellets helps your fish avoid illness.

If you buy these pellets, they will arrive in a container that fits neatly in your pantry and has a tight-fitting top to keep out air and preserve their freshness.

Unfortunately, you’ll need to break these pellets before feeding them to your fish because they’re too big.

However, if you’re looking for sinking fish food, this is one of the better options available.


  • Maintain a healthy diet
  • Promptly sunk
  • Wonderful presentation
  • Inexpensive


  • Fish food that comes in large, hard pellets that must be crushed before being fed to the fish.


A Cube of Hikari Bio-Pure Freeze-Dried Spirulina Brine Shrimp

Hikari’s Shrimp cubes are freeze-dried and combined with spirulina for added nutrition. This implies that each and every bite is beneficial. Brine shrimp are one of the greatest sources of high-quality protein in the world, which is essential for the proper functioning of most bottom feeders.

Smaller fish will be able to pick up Brine shrimp fragments from the cube since, as you may already know, Brine shrimp are quite little. Larger fish shouldn’t have any trouble biting off chunks of the cube’s larger size.

Pressing a cube against the tank wall attracts the fish for a more personal feeding experience.

The one negative is the potential messiness of this cuisine. However, this fish meal is of great quality and has no filler ingredients, so it will actually benefit the fish being fed it. The high price tags are indicative of the high quality of this item.


  • Superb protein
  • Doesn’t waste your time with fillers
  • Offers a nutritious meal plan.
  • Tasty


  • Messy
  • Pricey


Fruit & Veggie TetraMin Plus with Tropical Flakes

One of the best-tasting fish meals available now is TetraMin Plus Tropical Flakes. Because shrimp is a food that bottom feeders enjoy, our product features that flavor.

A fish tank full of fish that won’t even bother to eat since the flakes smell so good. Unfortunately, the deliciousness of the food also implies that you need to limit their intake to prevent them from becoming obese.

This delicious meal has a high protein content and is a good source of essential nutrients for your pet, including vitamins and minerals.

Furthermore, it is easily absorbed by the body. That’s great news since it means the fish will be able to keep their tank cleaner for longer because most of the food will be absorbed by their bodies. In addition, the water will not be tainted by the unconsumed flakes.

The nutritious content of these flakes, however, might diminish if they are exposed to air, so it’s best to keep them in sealed containers.


  • Delicious shrimp taste
  • Quickly absorbed
  • Don’t pollute the water supply!
  • Completely nourishing


  • At risk of losing nutritional value when exposed to air


We recommend Fluval Hagen Vegetarian Pellets

Fluval’s Vegetarian Pellets are formulated for herbivores and feature the superfood spirulina as the primary component. Carrots, spinach, peas, garlic, and cabbage are among the healthy vegetables included in this dish. Krill and herring contribute high-quality proteins as well.

Therefore, fish like Mbuna cichlids and silver dollars benefit greatly from this meal. The pellets settle to the bottom, making it easy for goldfish to consume them without having to gulp any air. If air gets into their digestive tracts, it might be harmful.

Only problem is, it’s not suitable for your carnivorous bottom feeders, thus you can’t serve it to them.


  • Nutritious
  • Rapid submersion
  • Excellent materials used


  • For use only by herbivorous fish
