More commonly known in the hobby as the Horseface Loach, the 'Banana Loach' is a highly specialized, elongated bottom-dweller. They are famous for completely burying themselves in the substrate with only their eyes protruding to watch for predators or prey. A soft, deep sand bed is absolutely mandatory; sharp gravel will severely damage their bodies and sensitive barbels.

Banana Loach Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Adult / Standard
The fully grown adult. Due to their long, rigid bodies and burrowing habits, they require a substantial tank footprint (at least 4 feet long) with deep, soft sand.
Same care requirements as the base species
Also known as: Adult Horseface, Full Grown
Juvenile (Grow-out)
Juveniles are commonly sold in the trade at a small size (around 2-3 inches). While they can temporarily reside in smaller aquariums, they will grow fast initially and eventually require a large tank with deep sand.

Banana Loach Care Guide Summary
The Banana Loach, scientifically known as Acantopsis choirorhynchos, belongs to the Loaches family group. Adults reach a maximum size of approximately 22 cm and have a eel body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the bottom zone of the aquarium and produces a medium level of biological waste.
To thrive, the Banana Loach requires a freshwater only aquarium with a minimum volume of 200 litres and a tank length of at least 120 cm. Water temperature should be maintained between 22°C and 28°C, with a pH range of 6–7.8 and a general hardness of 2–15 dGH. A moderate water flow is preferred.
The Banana Loach is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Adult / 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.
Banana Loach Habitat Setup
When setting up an aquarium for the Banana Loach, a moderate water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and smooth gravel or rounded substrate to protect their sensitive barbels. Keepers should note that expect substrate disturbance, so lightweight décor should be secured.
Banana Loach Compatibility Notes
Classified as peaceful, the Banana Loach 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 bottom zone can help reduce competition and territorial overlap.

Fish Similar to Banana Loach
Yoyo Loach
Botia almorhae
A popular, energetic, and boisterous bottom dweller native to the slow-moving and still waters of the Ganges basin (India/Pakistan). Named 'Yoyo' because the dark reticulated patterns on juveniles often resemble the letters Y-O-Y-O. As they mature, the pattern becomes a complex mosaic. They are excellent snail eaters but can be semi-aggressive/boisterous, making them unsuitable for shy or long-finned tank mates.
Zebra Loach
Botia striata
A highly active, beautifully striped bottom dweller endemic to the Western Ghats of India. Unlike some larger botiid loaches, the Zebra Loach is peaceful and stays relatively small, making it an excellent community fish. They are highly social, strict schooling fish that establish complex pecking orders. They are also famous for being voracious consumers of pest snails.
Kuhli Loach
Pangio kuhlii
A remarkably peaceful, eel-like bottom dweller native to the slow-moving forest streams of Southeast Asia. Famous for its orange and dark brown banding, the Kuhli Loach is an excellent scavenger. They are notoriously shy and nocturnal, requiring dense planting, leaf litter, and most importantly, a soft sand substrate to burrow in without damaging their delicate barbels. They must be kept in groups to feel secure and prevent severe stress.
Clown Loach
Chromobotia macracanthus
A highly popular but large-growing shoaling fish famous for eating nuisance snails. Known for their striking orange and black bands, they are highly social and must be kept in groups. They have no standard scales, making them sensitive to medications and prone to Ich, requiring pristine, warm water. They are known for their quirky behavior of sleeping on their sides or backs.
Dwarf Chain Loach
Ambastaia sidthimunki
An incredibly active, highly social, and peaceful nano loach. Known for its distinct chain-like pattern, this species is an excellent alternative to Clown Loaches for smaller aquariums. They are fantastic snail hunters. They must be kept in groups of at least 6 to feel secure and display their entertaining, hyperactive shoaling behavior.
Julii Corydoras (False Julii)
Corydoras trilineatus
Often sold in the aquarium trade as the 'Julii Cory', the False Julii (Corydoras trilineatus) is a peaceful, highly social bottom-dweller. It features a distinct reticulated (maze-like) pattern on its head and a prominent horizontal stripe down its body. As an obligate schooling fish, it must be kept in groups to thrive and feel secure. A soft sand substrate is absolutely critical to prevent the erosion of their sensitive foraging barbels.
