A highly specialized, peaceful Loricariid that perfectly mimics a submerged twig to hide from predators. Extremely slender and heavily reliant on grazing natural algae and biofilm from driftwood and plant leaves. They are highly sensitive to fluctuating water parameters and are easily outcompeted for food by faster tank mates.

Twig Catfish Varieties
Each variety inherits the species defaults above. Only differences are highlighted.

Juvenile (Grow-out)
Young Twig Catfish, commonly sold at 8-10cm. Extremely delicate and highly susceptible to starvation in newly set up aquariums. Must be monitored closely to ensure they are eating.

Twig Catfish Care Guide Summary
The Twig Catfish, scientifically known as Farlowella vittata, belongs to the Catfish family group. Adults reach a maximum size of approximately 22.5 cm and have a eel body shape with a slow growth rate. Classified as peaceful, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a medium level of biological waste.
To thrive, the Twig Catfish requires a freshwater only aquarium with a minimum volume of 110 litres and a tank length of at least 90 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 6–7.5 and a general hardness of 3–10 dGH. A moderate water flow is preferred.
Due to its specialist needs, the Twig Catfish is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Standard and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Twig Catfish Habitat Setup
When setting up an aquarium for the Twig Catfish, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include driftwood, which can serve as both a hiding place and a dietary supplement, an established tank with natural algae growth, as they depend on it as a primary food source, and dense planting to provide cover, break sightlines, and reduce stress.
Twig Catfish Compatibility Notes
Classified as peaceful, the Twig Catfish is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, boisterous or fast-moving tankmates may cause this species undue stress. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.
Who Twig Catfish Is Actually For
Twig Catfish is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially driftwood.
The most common mistake is buying Twig Catfish for looks first and only later discovering how its adult size, behavior, or bioload changes the whole tank plan. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

Fish Similar to Twig Catfish
Twig Catfish (Farlowella)
Farlowella acus
The Twig Catfish is an extremely elongated, master-of-camouflage suckermouth catfish from South America. True to its name, it mimics a dead twig perfectly, spending most of its time motionless on branches or plant leaves. It is a specialized aufwuchs and algae grazer that requires a mature tank, high oxygenation, and plenty of driftwood. They are completely peaceful but highly sensitive to fluctuating water parameters.
Whiptail Catfish
Rineloricaria sp.
A highly cryptic, peaceful, and extremely slender catfish that mimics a twig or dead leaf. They are excellent scavengers and biofilm grazers that require smooth sand and driftwood to thrive. They are completely non-aggressive, lack the heavy armor of larger plecos, and do well in peaceful community setups.
Royal Farlowella Catfish
Sturisoma panamense
A striking, elongated catfish known for its twig-like appearance, prominent dorsal fin, and long tail filaments. They are excellent grazers that spend their time clinging to driftwood, broad-leaved plants, and aquarium glass. Highly peaceful but sensitive to poor water quality and starvation. A constant supply of biofilm, algae, and driftwood is essential.
Common Whiptail Catfish
Rineloricaria eigenmanni
A highly distinctive, slender, and peaceful bottom-dwelling catfish from South America. Known for its extremely elongated tail and excellent camouflaging abilities. They are non-aggressive grazers that feed on biofilm, aufwuchs, and sinking foods. Their rigid, twig-like bodies mean they need broad, smooth resting places.
Chocolate Loricaria (L062)
Loricaria cataphracta
A fascinating, peaceful, and slender whiptail catfish from South America. They feature a heavily armored, flattened body and an under-slung sucker mouth. In the aquarium, they are largely nocturnal and enjoy partially burying themselves in fine sand. Unlike strict algae-eating plecos, they are omnivores leaning towards carnivore, requiring meaty foods like frozen bloodworms and sinking carnivore pellets.
Loricaria lundbergi
Loricaria lundbergi
A slender, highly camouflaged whiptail catfish native to the deep, blackwater river channels of the Rio Negro and Rio Madeira basins. Unlike many suckermouth catfish, they are primarily insectivores and detritivores, actively sifting through the substrate for aquatic insect larvae rather than eating algae. They are peaceful, facultative air-breathers that require a soft sand substrate to prevent damage to their delicate mouths.
