Botia kubotai
A strikingly patterned and highly active river loach native to Myanmar. As they mature, their distinct stripes break into intricate golden 'polka dots' over a dark body. Highly social, they must be kept in groups to establish complex pecking orders; keeping them in too small numbers leads to hiding or aggressive lashing out. They are excellent at controlling snail populations but require well-oxygenated water and a spacious footprint.
Acantopsis choirorhynchos
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.
Botia dario
A strikingly patterned, highly active loach native to the Brahmaputra and Ganges basins. Like most Botiid loaches, they establish complex social hierarchies and must be kept in groups to prevent stress and aggression. They are excellent snail hunters but require a soft, sandy substrate to protect their delicate sensory barbels from abrasion.
Pangio oblonga
A peaceful, eel-like bottom dweller known for its solid dark brown to black coloration. Like other Kuhli loaches, they are strictly nocturnal scavengers that require a fine sand substrate to burrow and sift through without damaging their delicate barbels. They are highly social and must be kept in groups to feel secure and exhibit natural behaviors.
Yasuhikotakia modesta
A large, active, and highly social river loach recognized by its bluish-grey body and vividly colored fins (yellow, orange, or red). They are known for making audible 'clicking' noises. While fascinating, they are boisterous and can be aggressive or fin-nipping if not kept in a proper hierarchy; keeping them in groups of 5+ is mandatory to diffuse conspecific aggression and prevent them from terrorizing tank mates.
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.
Misgurnus anguillicaudatus
A large, highly active, and deeply social cold-water loach. Famous for their erratic swimming patterns in response to barometric pressure changes (hence 'Weather Loach'). They are entirely unsuited for tropical temperatures and require fine sand to fulfill their natural burrowing behaviors.
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.
Beaufortia leveretti
A fascinating bottom-dweller adapted to fast-flowing mountain streams in Asia. It features a unique, flattened body allowing it to cling to smooth rocks in heavy currents. It requires highly oxygenated, cooler water (18-24°C) with strong flow. Often confused or mislabeled in the trade with its smaller, more common cousin, Beaufortia kweichowensis. They are specialized grazers that feed heavily on biofilm and algae.
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.
Paracanthocobitis botia
A highly active, rheophilic (current-loving) loach native to fast-flowing streams in South Asia. Known for their intricate mottled patterns and 'zipper-like' lateral line, they are boisterous and establish clear social hierarchies. They must be kept in groups to prevent bullying and require well-oxygenated water with a smooth substrate to protect their delicate barbels.
Schistura robertsi
The Phuket Loach is a small, active stone loach native to fast-flowing, clear streams in the Malay Peninsula and southern Thailand. Like most Schistura species, they are highly territorial bottom-dwellers that require highly oxygenated water with moderate to high flow. They should be kept in setups with smooth river stones to break lines of sight and minimize aggression.
Sewellia lineolata
A fascinating, highly specialized loach adapted to fast-flowing, oxygen-rich rapids. They have a flattened, ray-like body allowing them to cling to smooth rocks where they graze on algae and biofilm (aufwuchs). They strictly require strong water flow, high dissolved oxygen, and cooler temperatures. Males frequently engage in visually striking but harmless territorial 'battles' over prime feeding rocks.
Yasuhikotakia morleti
A strikingly patterned but notoriously aggressive loach from the Mekong basin. Named for the prominent black stripe running down its back, the Skunk Botia is highly territorial and prone to nipping the fins of slow-moving or long-finned tank mates. They are exceptionally efficient snail hunters but must be kept in groups of 5 or more to disperse their complex, hierarchical aggression. They require a soft, sandy substrate to protect their sensitive barbels from damage.
Gastromyzon punctulatus
A highly specialized, rheophilic (flow-loving) fish adapted to cling to rocks in fast-moving streams. Their modified fins act like suction cups. They graze constantly on biofilm and algae. To thrive, they require cooler, highly oxygenated water with strong currents (like a river manifold or powerhead setup) and plenty of smooth river stones.
Schistura balteata
The Sumo Loach is a fascinating, highly active bottom dweller native to fast-flowing hillstreams in Myanmar. Named for their aggressive, 'wrestling' matches over territory, they require highly oxygenated water, strong flow, and plenty of visual barriers like smooth river stones. They are highly intolerant of conspecifics and other bottom dwellers in small tanks.
Syncrossus hymenophysa
A large, highly active, and notably aggressive loach recognized by its striking vertical stripes. Unlike most peaceful botiid loaches, the Tiger Loach is highly territorial and a notorious fin-nipper. They are social but possess a strict, often violent hierarchy; they must be kept in groups of 5+ to disperse aggression. Excellent at eradicating snails, but require fast-moving, robust tank mates (e.g., large barbs).
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.
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.
