Kuhli loaches are active scavengers that scour the bottom of your aquarium for uneaten fish food, preferring sandy or fine gravel substrate with plenty of hiding spaces and hiding places. Although mostly nocturnal, they will come out for meals.
Plecostomus catfish (Hypostomus plecostomus) can often be found at fish stores; however, as they reach over one foot long in maturity they’re best suited for tanks larger than 75 gallons and tend to feed on algae, biofilm and decayed plant matter.

Bristlenose Catfish
Ancistrus cirrhosus or “Bristlenose catfish,” are unique freshwater tank inhabitants that add both color and texture. With their suckermouth at the bottom of their bodies, Bristlenose catfish use this suckermouth to attach themselves to rocks, decorations and substrate and consume algae from these surfaces. As peaceful community fish they can coexist peacefully alongside similar species like Mollies, Tetras, Guppys Angelfish (and even snails!). Easily identified due to their bony plates covering bony plates over their wide heads than their Pleco counterparts making identification easy!
Ancistrus species fishes are nocturnal fish that do best with low lighting in the tank. Since these grazers feed on both plant matter (such as algae wafers, spirulina flakes or granules) as well as protein-rich foods like bloodworms – Ancistrus fish also serve as excellent tank cleaners that will eat any detritus that accumulates within your aquarium and protein rich foods like bloodworms – they make an ideal alternative to growing Pleco species which often reach monstrosities in size!
Oto Cats
Otocinclus catfish (Otoclinus vittatus) is one of the most frequently seen bottom feeders used in freshwater aquariums, often seen shoaling together. Their highly active nature means they enjoy grazing algae off aquarium plants, tank glass surfaces, and ornaments to feed.
They make great aquarium cleaners, searching through substrate to locate any uneaten food or dead organic matter that has not been consumed by other fish or organisms. Oto catfishes are herbivorous fish; in nature they feed on algae, bacteria, and plant matter for sustenance; it is important that their tank contains ample supply of algae so they have sufficient nutrition for survival.
Add variety to their diet with commercial algae wafers and pieces of blanched vegetables such as zucchini that have been sitting in water for 24 hours. Just be wary not to overcrowd your aquarium with these fish, as they could devour any new algae quicker than it can grow back.
Corydoras
Corydoras fishes are small bottom-dwellers known for using their barbels to forage on substrate and filter food items from it, often becoming curious of any changes or differences they encounter – which can present problems when housed with other aggressive fish species.
Corydoras require at least a 10-gallon tank as their minimum living environment, filled with sand and gravel and plants/bogwood for hiding spots. Because these fish prefer living together in schools of their same species, an aquarium with dark substrate should provide optimal conditions.
They make great additions to a community tank and can eat leftover food from other fish in the tank! In addition, they serve as an effective clean-up crew by sifting through substrate and eating any uneaten food or debris that might accumulate. Danios make great tankmates for gouramis, tetras and other smaller species of fish as well as snails and shrimp; snails may even get along well!
Kuhli Loaches
Kuhli Loaches (Pangio kuhlii) are bottom-dwelling eel-like fish that make excellent tank companions. At first glance, these species resemble snails or eels rather than traditional fish due to their slim bodies with small fins and alternate dark and light colored bands wrapping their bodies.
They tend to be shy and reclusive by nature, preferring to remain hidden during the day while coming out at night to explore their environment in search of food and waste. They thrive best when living in an aquarium with plenty of plants providing hiding spaces.
Kuhli loaches can be found living wild in slow-moving rivers and clean streams in Southeast Asia. Though hardy fish, these unique aquatic species thrive best under optimal conditions in captivity such as low lighting levels and soft waters with pH balance between 5.5 to 6.5 and no higher than 5.0 dGH levels.
Fish tanks provide both beginner and experienced aquarists alike with an opportunity to experiment. A well-anchored substrate will protect them from injuries caused by jagged gravel, while environmental enrichment such as rocks, new plant species and hiding places provide environmental enrichment and an enriching experience for all inhabitants of the aquarium. They’re an ideal option for beginners or veteran aquarists.
