Most Popular Bottom Feeders for an Aquarium

Creating a natural habitat for your wildlife is one of the most interesting aspects of owning a fish aquarium. In addition to fish, rocks, gravel, plants, and manmade filters, the most ideal fish tank community includes wildlife that would clean the tank in a natural body of water. Fortunately, you have many great options, as some of the top bottom feeders for an aquarium are actually very fascinating to watch as well.

Why You Need Bottom Feeders in a Fish Tank

Bottom feeders eat the algae, decaying plants, dead animals, larvae, and natural debris that is created in a fish tank. As a result, they help to maintain an ideal ecosystem and keep the alkalinity of the water at an optimal level. The bottom feeders assist the manmade filters in doing their job, and they also enhance the aesthetic appeal of the aquarium.

Even if you do add bottom feeders into your tank, you should also include plants, gravel, and rocks as well. All of these elements together help to create the best environment for your fish and other wildlife.

Top Options for Bottom Feeders for an Aquarium

1. Shrimp

Shrimp are popular because they add a pop of color to a fish tank, and they’re tough critters. One of the most popular is the cherry shrimp, which is usually a beautiful crimson color. Other shrimp commonly used as bottom feeders for an aquarium include:

  • Crystal shrimp
  • Bumblebee shrimp
  • Amano shrimp
Red Cherry Shrimp are one of the top bottom dwellers for a fish tank.

2. Snails

While you don’t want snails to infest your freshwater tank, if you intentionally add a snail to a tank and maintain it properly, it can be one of your greatest assets. The most effective may be the Malaysian trumpet snail, but other popular snails are nerite snails and mystery snails.


3. Catfish

Catfish are relatively peaceful animals that are omnivorous, so they can eat insect larvae, clams, fish, plants, snails, and crayfish. The peppered cory catfish is one of the most common species used as bottom feeders. Other types include:

  • Channel catfish
  • Flathead catfish
  • Blue catfish
  • Brown bullheads
  • Yellow bullheads
  • Glass catfish
  • Pictus catfish
  • Otocinclus catfish
  • Twig catfish

4. Crayfish

Crayfish add a certain appeal to an aquarium, and they’re excellent bottom feeders. They’re a bit shy though, so you may find them hiding in secret spots in your aquarium.


5. Loaches

Loaches are among the most popular bottom dwellers for an aquarium in general, but they can be a bit aggressive. Commonly used loaches include:

  • Yoyo loaches
  • Dwarf loaches
  • Zebra loaches
  • Clown loaches

6. Plecos

Members of the catfish family, several different types of plecos are often used to keep those fish tanks clean. They grow larger than some other types of bottom feeders and can be very strong. Bristlenose plecos, for example, can grow to four inches and often have large whiskers. A clown pleco is also a popular bottom feeder.

7. Algae Eaters

Members of the carp family, Siamese algae eaters and Chinese algae eaters are effective in clearing algae out of your tank. They tend to have a stripe along their bodies and can be attractive additions to your fish tank. The downfall is that they can become very aggressive when they’re fully grown.
