Freshwater aquarium fish bottom feeders are easy to care for and make beautiful additions to any tank. Some even help clean up uneaten food!
Some fish like the Kuhli Loach may look strange, but they’re an absolute joy to watch! These unique-looking species prefer heavily planted tanks with plenty of dark corners for hiding.

Cory Catfish
Cory catfish are predators, using their whisker-like barbells to search for food in lakes and streams. Cory catfish thrive when placed in tanks with fine sandy substrate, featuring plants, rocks, or driftwood for hiding places; they’re curious creatures, willingly exploring any changes that occur in their environment. While Cory cats can consume many forms of food – from live to frozen and flake varieties – feeding is important.
Aquarists who maintain an aquarium often find them living happily alongside otocinclus catfish or tiger barbs, since these nonaggressive fish thrive when living peacefully together in community tanks. When living wild, however, they release toxins to defend against predators while covering themselves in armored scales to shield their skin and reduce vulnerability against attacks from other fish species. They spawn together so their eggs are protected.
Shrimp
Shrimp are popular choices among freshwater aquarium owners due to their ease of care. As algae eaters, shrimp can help clean your tank of debris.
Freshwater aquarium plants can add aesthetic value and versatility to almost any tank setup, providing shelter and hiding spaces for shrimp and other creatures in your aquarium. With so many types of Java ferns and Anubias species providing perfect hiding places for shrimp.
Snails make excellent bottom feeders in your freshwater aquarium fish bottom feeder, as they require minimal care and upkeep while being colorful, particularly those from Neritina sp.). Snails serve as excellent aquarium cleaners by searching through all corners and crevices looking for algae; additionally, they’ll eat leftover food too if there’s any left behind! They can breed in their freshwater tank provided both males and females are present; otherwise eggs won’t be laid.
Otocinclus
Otos are great additions to any aquarium because they eat algae naturally while helping clean the tank at the same time. Best kept in groups and much like Corydoras, Otos reproduce by depositing adhesive eggs onto plant leaves and surfaces around their environment.
Surgeonfish are relatively simple fish to care for and can cohabitate peacefully with other non-aggressive freshwater fish, such as guppies and angelfish. Their natural environment includes shallow, slow-flowing rivers and streams where algae-covered rocks and substrate are present; to replicate this environment in your tank simply provide soft fine-grain sandy substrate decorated with driftwood, caves and plants such as staurogyne repens plants as decorations; they will spend most of their time methodically feeding on algae – making these freshwater bottom feeder fish ideal candidates!
Twig Catfish
Twig catfish (Farlowella acus) appear as thin branches in an aquarium, providing protection from predators. They can grow to between 7-9 inches long. As adept scavengers, most of their nutrition will come from the tank substrate; however, you can supplement this with additional foods. These fish prefer herbivorous diets so provide fresh vegetables (boil or soften spinach, kale, zucchini medallions and lettuce for example), algae wafers or tablets or as occasional treats! Daphnia brine shrimp or mosquito larvae can also make for excellent treats!
Twig catfish may be kept in a community tank, although they tend to prefer being kept with members of their own species. A sandy substrate mimicking their natural habitat is preferable; tall aquatic plants such as Vallisneria or Amazon swords provide both hiding spaces and food sources for these twig catfish.
Yoyo Loach
Yoyo loaches are highly active freshwater bottom feeders, so they need an aquarium that can keep up with their energy. Although shy at first, once settled into their environment they become much more active and explore their surroundings. Small hiding spaces are preferred by this species while rocks or driftwood with sharp edges should be avoided to avoid fin snags from sharp objects like sharp rocks or driftwood edges; male yoyo loaches tend to have slimmer bodies than females and mature males often display red coloring around their barbels indicating maturity.
Yoyo loaches, like other members of the Botia genus, are omnivorous fish. These predators will consume any plant food they find available and even scavenger for snails by sucking out their shells and sucking out snail eggs directly.
