Updated: August 4, 2023

While many fish are sold in the pet industry for decoration, some make good additions to the bottom of an aquarium. These fish help clean up any waste in your aquarium; they clean it up by eating it and expelling it out through their gills.

This is beneficial for the owner because this waste usually makes the water in your tank unsanitary and much more dangerous for fish to live in. Cleaning up this mess will keep your pet safe from any hazardous toxins that may result from it.

In this article, we will discuss the best bottom feeder fishes that you can get for your aquarium.

List Of All 14 Bottom Feeder Fishes

The following list is 14 bottom feeder fish for aquariums. This list also consists of a description of each one, the primary care of each fish, and some information on where they may originate from.

It is important to remember that many of these fish can grow quite large while some are completely harmless.

This may cause difficulties for the owner because larger bottom feeders require a bigger tank. Some owners prefer to make it work; others decide their pet will go elsewhere if they don’t have room for the fish.

1. Plecostomus

Scientific nameHypostomus plecostomus
Origin: Amazon river of Brazil
SizeUp to 15 inches
Lifespan5 to 10 years
Activity LevelPeaceful
Care level:Easy
pH level:6.5-7.5
Temperature:72-78 °F

The plecostomus is a great addition to almost any aquarium that it is placed in. They are relatively easy to care for and do an excellent job cleaning up your tank’s waste.

Bottom Feeder Fish : Plecostomus

The plecostomus is also a great-looking fish; they can be any color from yellow, brownish, or grey. They also come with many different patterns, such as blotches or stripes on their sides, and can be spotted or unspotted.

They are usually very friendly fish and will not bother any of the other fish in your aquarium, but on occasion (and with some plecostomus) they can become territorial. This fish also has whiskers that it uses to find food on the bottom of your tank; they use these whiskers as feelers to search for food that may be on the bottom of your aquarium.

Plecostomus get most of their nutrients from algae, so they are usually kept in tanks with many plants.

They have a sucker-like mouth used to attach themselves to surfaces and rocks. The plecostomus has been known to be very peaceful and tolerate other fish who happen to share territory.

Plecostomus are originally from South America. They prefer water that has a pH level of 6.0-8.0 and temperatures between 72-78 degrees Fahrenheit. This fish usually inhabits stagnant water in the wild, so they should be provided with lots of plants to help keep the water clean and rocks to hide.

Plecostoms are bottom-dwelling fish with sucker mouths to help them stick on the tank floor. They are large, heavy-bodied fish with small fins.

These guys can grow up to 20″ long in an aquarium, so they need a decent-sized tank (55 gallons or more) to live in. Plecostoms are very dull colored and have a brownish-grey coloring.

These fish require a meaty diet consisting of brine shrimp, blood worms, krill, and any other food that is high in protein. They also require a bottom substrate to bury themselves to search for food. Plecostoms are nocturnal, so they like it best when the aquarium lights go out, and they can find their food.

This is a very large group of fish known for eating vegetation and algae and cleaning up the bottom of your tanks.

They range in size from a few inches to several feet long. The peacock pleco (pictured above) is a common example of how you can get creative with what kind of plecos you want.

It is important to ensure your plecostomus stays healthy by feeding it vegetable matter, algae wafers, and sinking pellets.

The clown loach is a great addition to your aquarium because of its unique look, gentle nature, and ability to clean algae off rocks in your tank.

Clown loaches have a special way of removing algae- they have a pair of suckers on their undersides that they use to attach themselves to rocks and then slowly move across them, eating the algae as they go.

Their diet consists mainly of vegetable matter, so you can feed them boiled zucchini slices from time to time if you want. Algae pellets and tablets are a good option.

The clown loach will reach up to 13″ long, and is a social fish. It will get along with other bottom feeders but may fight with its own kind, so keep two of them together in your tank.

Keep this fish in an aquarium that’s at least 20 gallons, and make sure the water stays clean because this fish likes to sift through the dirt on the ground to find food. It eats algae, plants and any leftover food that sinks to the bottom.

The clown loach is a very active fish, so make sure your tank has some places for them to hide. Hiding places can be formed by driftwood or rocks piled together on the ground of your aquarium. Clown loaches also need a lot of territories to swim around in.

Temperature:75-85 °F

They can be kept with other bottom feeders without a problem, but they should not be put in tanks with large or mean fish. Because shrimp are sensitive to environmental changes, they should be kept in groups of at least 3 so one or more can act as a lookout if another is hiding.

Bottom Feeder Fish : Shrimp

These shrimp spend most of their time on the bottom of the tank eating food there and looking for small waste particles to eat. They will occasionally venture into other areas but not far from where they started.

The ghost shrimp is a freshwater variety that is white with grey markings. There are also saltwater shrimp that are transparent with purple markings, but it is the freshwater version that this article refers to.

Their coloring tends to be different because of their environment; for example, if they live in a dark tank, they will have crystal clear bodies instead of white because it provides camouflage. They enjoy hiding places like plants, rocks, and large PVC pipes.

This bottom feeder only needs to be fed 1-2 times weekly because they are inactive.

The ghost shrimp prefers a water temperature of 72 to 82 degrees Fahrenheit. They need an environment with hiding places like plants, rocks, or PVC pipe pieces. The optimal pH level range is 6.

These shrimp are considered “large, ” meaning they will only grow up to about 1 inch long. They eat leftover food and algae on the bottom of your tank. They are peaceful and will not bother any fish in your aquarium.

They should be kept in groups of 3 or more because shrimp are very sensitive to environmental changes, and one or two may hide if another is scared.

Bottom Feeder Fish : Synodontis Catfish

These bottom feeders are nocturnal, so you will not see them during the day because they will hide until nightfall. Then these fish are very active and can be seen feeding at this time.

Their bodies are triangular with wide back fins that allow these fish to swim very fast.

The best way to feed them is by purchasing sinking pellets for bottom feeders or catfish tablets that slowly dissolve near the bottom of your aquarium. These fish are scavengers so they should be given sinking food 2 to 3 times daily.

Synodontis catfish can live approximately 5 years in captivity, but the average lifespan is 3 years.

They are a popular bottom feeder because they can be kept with other Synodontis catfish as long as you have enough space for them to hide during the day.

These bottom-feeders prefer an aquarium that’s at least 10 gallons, but they can live in smaller tanks if there are plenty of hiding places.

They are not difficult to care for if you provide them with ideal water conditions, stay well-fed, and keep them in a large enough tank.

They only eat live food because these bottom feeders will starve otherwise. You can feed them crickets or earthworms as long as they are small enough for Synodontis to eat. It feeds on plant matter, small crustaceans like brine shrimp, and even algae in the wild.

Synodontis Catfish are easy for beginner aquarists with low experience to care for because they eat anything you put into the tank (meaty foods like bloodworms or brine shrimp), and their water requirements are not too strict.

They will help keep the bottom of your freshwater aquarium clean because they feed on algae and dead plant matter, but it is important to note that they will eat any fish that they can fit in their mouths.

Synodontis catfish can grow up to 4 pounds in the wild, but most only grow up to 1 pound in the aquarium.

10. African Butterfly Fish (Freshwater)

Scientific NamePantodon buchholzi (freshwater)
Origin: South of the Sahara Desert.
Size5 inches
Lifespanup 5 to 6 years

Bottom Feeder Fish:  African Butterfly Fish

Its body is typically adorned with shades of brown, green, and black, helping it blend seamlessly into its natural habitat.

Due to its unique hunting behavior, providing a suitable aquarium setup for the African Butterfly Fish is important.

A well-planted tank with floating vegetation, such as Amazon frogbit or water lettuce, mimics its natural environment and offers the fish the cover it needs for successful hunting. Maintaining a calm water surface is essential to allow the fish to execute its hunting strategy effectively.

African butterfly fish are best kept in aquariums that have live plants because these fish will eat them if they can get to them or if there is no algae for them or other bottom feeders to eat.

They should only be fed algae-based foods because they will not survive on any flake food.

You can feed African butterfly fish algae wafers or catfish pellets. They should only be fed once daily so you don’t feed them too much food, which goes to waste. Just a few flakes or pellets will do the trick.

These fish are peaceful and can be kept with other African butterfly fish, but they will also do well alone because they prefer a solitary life. They won’t bother any other fish in the aquarium, but they may quarrel with other bottom feeders that want to eat what’s on their menu.

They are very delicate fish, so you will need to provide them with the perfect water conditions for them to stay healthy.

Keep the pH level at 6.5, and maintain a temperature of 75-80 F. African butterfly fish can’t tolerate high levels of nitrates or ammonia in the water, so it is essential to have a healthy bio-filter in the aquarium.

They can be kept with other bottom feeders because they are peaceful, but you should only keep them in schools of 3 or more fish.

They look very pretty when they are swimming around in an aquarium, especially if the other fish in the tank are fast swimmers. Their unique colors and patterns make them one of your aquarium’s most attractive bottom feeders.

These fish need a lot of hiding places because they usually hide when there is too much activity in the tank. You must keep plenty of plants and rocks because they will swim into them when stressed.

These fish are very active, so your tank needs to be large enough for them to swim around freely without bumping into things. They aren’t fussy regarding water conditions, but that doesn’t mean you should neglect their tank.

You need to keep the aquarium clean and do water changes at least once a week because bumblebee gobies produce excess waste.

They can make fantastic pets for any age group. They are very easy to care for and don’t require much attention.

12. Harlequin Rasbora (Freshwater)

Scientific NameCrossocheilus siamensis
Origin: southeast Asia.

Bottom Feeder Fish: Harlequin Rasbora

These fish stay close to the bottom of the tank, where you will find them most of the time if they are healthy and happy.

They prefer small, dimly lit aquariums because their colors look best in that type of environment. It would help if you kept this fish in a school or at least 3 or 4 because they like to be with their own species.

You should give them plenty of hiding spots in the tank because they like to rest in dark places when they can’t find any food.

They don’t need a huge aquarium, but it needs to be large enough for them to swim around freely and search for food. They don’t like bright light very much and like dimly lit areas of the tank. You should keep them in soft, slightly acidic water with a neutral pH level.

They won’t bother any other type of fish in your tank as long as they stay away from them, but you need to keep this fish with fast swimming species because it isn’t a very good swimmer.

They prefer living in groups because it makes them feel more comfortable, but they don’t really need a group to survive.

13. White Cloud Mountain Minnow

Scientific NameTanichthys albonubes
Origin: Asia and Indonesia
Size3 inches
Lifespan3 to 4 years
Care level:Easy
pH level:7.6
Temperature:68° F

These fish are very peaceful, so they shouldn’t cause any problems for other types of fish in your tank. They should only be kept with other species with a similar temperament to keep things calm and quiet.

Bottom Feeder Fish: White Cloud Mountain Minnow

The males will fight each other if you put more than one together, but the females shouldn’t have any problems living together.

These fish eat a lot of different types of food, but they especially love algae and live plants. You will need to give them a large tank so that there is plenty of space for these plants as well as the fish, because the plants are an important part of their diet.

They should be kept in groups with 5 or more minnows in the same tank at all times because they are very social.

They will feel more comfortable if you keep them with 5 or more minnows, but it is possible to keep them with only one other minnow.

These fish shouldn’t be kept with aggressive types of fish, so avoid putting them in tanks with cichlids and larger types of catfish. They are really only compatible with smaller, peaceful species that won’t bother them or try to eat them.

These fish are easy to care for if you make sure the tank has plenty of plants because they need their algae fix.

14. Oscar Fish

Scientific NameAstronotus ocellatus
Origin: South America
Size20 inches
Lifespan10 years
Care level:Easy
pH level:6.8
Temperature:68° F

When they are larger and fully grown, Oscar fish become very territorial and aggressive, and they will constantly fight with each other if you put them in the same tank.

It would be best if you only kept these fish alone because they won’t calm down until their tank is free of any other species.

Bottom Feeder Fish: Oscar Fish

Oscars eat a lot of different types of food, but they especially love live meat, like worms and insects. They also eat crustaceans, fish, snails, crawdads, earthworms, and aquatic plants.

Oscars need a huge tank with plenty of hiding places that are big enough for them to hide in comfortably because they are very territorial and shy when they are little fish.

These fish need a very large tank because they will grow up to 12 and 20 inches long. You must have plenty of space for them to swim around comfortably in the tank, so your Oscar can live a healthy life.

You also want to leave room for any plants or rocks that you want to put in the tank with them because they are important for their diet.

These fish will eat almost anything you feed them, so they are really easy to care for. They don’t need any special types of food or supplements to stay healthy and alive, so it is very easy to keep them happy.

They also like to dig up the substrate around the tank, which can damage your live plants. They should be kept on their own unless you want to clean up after them constantly.

These fish also prefer to live in tanks that are at least 55 gallons, so there is plenty of room for them to grow and move around. They will fight each other if you put too many fish in one tank so they should only be kept by themselves or with a small group of 3 or 4.

These fish aren’t very active, so their tanks don’t need to be filled with plants and things that they can hide under. You can decorate their tank with fake plants and stones because Oscars don’t like exploring new environments, so they will stay in one section of the tank if you give them something to look at.

If you want to keep these fish as pets, put a lot of live plants in their tanks because they won’t touch the real stuff and they like to hide under them when they feel threatened.

They will eat any food, but you should save the seafood and take it out after 24 hours because the meat will go bad and make your tank smell bad.


These are the 14 Bottom feeder fish for your aquarium. You can keep more than one of these fish in the same tank as long as you have a big enough aquarium with plenty of hiding places so they feel safe. Make sure you provide them with plenty of food. These fish are very easy to care for and don’t require much attention at all.

They are very peaceful, but they may nip the fins of other bottom feeders when they feel threatened. Make sure you keep them with fast swimming species because they are quite slow swimmers and don’t have a lot of stamina.
