The Best Clean-Up Animals for your Aquarium

Below are some species of snails that are excellent cleaners for an aquarium. We must specify that these are suitable for saltwater aquariums, so they will only be a good option if you have saltwater fish:

Tectus niloticus

This type of snail is certainly big, reaching 15 cm (6 in). It is recommended for larger aquariums. It has high food requirements so it will serve as a powerful cleaner. You should not have more than one Tectus niloticus snail per 100 liters. These snails are also known for their ability to help maintain the ecological balance of the tank by controlling algae growth efficiently.

Turbo lamiferus

This species is somewhat smaller than the previous one, but it still measures a considerable 9 cm (3.5 in). It is perfect for living with fish with a big appetite or aggressive fish, because its shell is hard and thick to protect it. While not exactly a big eater, the Turbo lamiferus snail will help you to remove small debris from the bottom of the aquarium. Additionally, its presence can significantly reduce the need for frequent tank cleaning.

Nerites albicella

These snails are perfect clean-up animals for your aquarium, as they will help you excellently control algae and they are quite resistant. However, we do not recommend keeping Nerites albicella snails in an uncapped aquarium as they tend to escape and this can cause them to die. They are very compatible with aggressive fish due to their strength and their shell will grow to a bigger size. Their ability to thrive in varying conditions makes them a versatile choice for many aquarium enthusiasts.

Astrea tectum

This snail species is smaller, measuring around 4 cm (1.6 in). Astrea tectum snails are very active and voracious and you will be surprised at how often they search for food. They are perfect for tanks with diatom algae. Their constant movement and feeding habits make them invaluable in maintaining the cleanliness of the tank.

Certain types of fish, especially catfish, are great clean-up animals for your aquarium, as they feed on the bottom of the tank. The most popular cleaning fish include:

Corydoras

Corydoras are a very popular kind of freshwater catfish. Among the best clean-up catfish you can find the peppered catfish, also called blue leopard corydoras or Corydoras paleatus. However, you must make sure you find a catfish species that suits the temperature of your aquarium. These fish are social creatures and thrive better in groups, which also enhances their cleaning efficiency.

Hypostomus plecostomus

Also known as common pleco or suckermouth catfish, this type of fish is a voracious algae eater, so they are suitable for aquariums with overpopulated flora. Common plecos are very popular and well-known cleaning fish, and they are present in many aquariums around the world. Their adaptability to various water conditions further adds to their appeal.

Otocinclus

This kind of algae-eater catfish is perfect to remove those green crystals remaining in your aquarium. Otocinclus catfish or dwarf suckers are also a resistant type. They are particularly valued for their gentle nature and efficiency in maintaining a clean environment without disturbing other inhabitants.

Wrasses

The wrasse family or Labridae include hundreds of different fish, all of them known for cleaning aquariums. The bluestreak cleaner wrasse (Labroides dimidiatus) in particular is an excellent cleaner for tropical reefs, so it is ideal if you have an aquarium with tropical fish as well as corals and anemones. Their symbiotic relationship with other fish can significantly enhance the health of the tank's ecosystem.

Gobies

The goby family or Gobididae are also excellent cleaners. While they are fish, their function in an aquarium is quite similar to that of crustaceans. For instance, gobies usually remove ectoparasites from other fish, which is very beneficial. Their unique cleaning behavior not only helps maintain the tank's cleanliness but also improves the overall health of the fish population.

Starfish have a very important role in cleaning oceans, because they don't just feed on small particles. In fact, a group of 2,000 starfish is able to shred a seal in 6 hours. Starfish are a perfect choice to clean saltwater aquariums.

Archaster typicus

The sand or sand-sifting star is a nocturnal species. Although this kind of cleaning starfish likes being covered in sand, it certainly also enjoys climbing the glass or the different elements in the aquarium. Sand starfish feed on anything, and also help by removing the sand. Their nocturnal habits ensure that they work on cleaning the tank even when other inhabitants are less active.

Ophiuroids

The ophiuroid group, also known as brittle stars, is closely related to starfish, although they are not exactly starfish themselves. There are many different species of ophiuroids, but in general, they are not recommended for beginners since their survival depends on a very specific environment. However, ophiuroids are excellent cleaners for the bottom of saltwater aquariums. Their delicate nature and unique mode of feeding make them fascinating yet challenging additions to any aquarium.

Sea cucumbers, just like starfish, are animals that clean the seabed. In general, sea cucumbers are more suitable for people with some experience in keeping aquariums. They should only be incorporated when the aquarium is well-grown. Some types of sea cucumbers to clean up your aquarium include:

Colochirus robustus

The robust or yellow sea cucumber mainly feeds on zooplankton and phytoplankton, but it also helps to get rid of bacteria. As their name indicates, yellow sea cucumbers are brightly colored and have an enchanting appearance. Their vibrant color not only adds beauty to the tank but also serves as an indicator of their health.

Holothuria spinifera

Unlike the yellow sea cucumber, the brown sandfish or Holothuria spinifera will feed on virtually any other living matter at the bottom of the aquarium. This species of sea cucumber is not at all conscientious and extremely effective as an aquarium cleaner. Their ability to process and recycle waste makes them indispensable for maintaining a clean and balanced aquarium environment.
