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.

Standard
The standard form. Juveniles show distinct 'YOYO' banding which breaks up into a darker reticulated net pattern as they reach adulthood. Must be kept in groups of 5+ to disperse hierarchy aggression.

Yoyo Loach Care Summary
The Yoyo Loach, scientifically known as Botia almorhae, belongs to the Loaches family group. Adults reach a maximum size of approximately 15 cm and have a fusiform body shape with a moderate growth rate. Classified as mostly peaceful, this species primarily occupies the bottom and mid-level zones of the aquarium and produces a medium level of biological waste.
To thrive, the Yoyo Loach 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 30°C, with a pH range of 6–7.5 and a general hardness of 3–12 dGH. A moderate water flow is preferred. To replicate their natural habitat, the tank should include sand (sifters), smooth gravel (sensitive barbels), driftwood (digestion/hiding), and plants - densely covered.
This species should be kept in groups of at least 5 to reduce stress and encourage natural behaviour. Keepers should be aware that this species may nip the fins of slow-moving or long-finned tankmates, will eat snails, and is primarily active at night or during twilight hours. The Yoyo Loach is typically available in one standard form.
Similar Species
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 Gourami
Trichogaster lalius
A peaceful to semi-aggressive labyrinth fish native to South Asia. Famous for their brilliant metallic blue and red stripes. While generally suitable for community tanks, males are territorial toward each other and similar-looking fish. They are sensitive to water quality and prone to Iridovirus if stressed. Requires access to the surface to breathe.
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.
Siamese Algae Eater
Crossocheilus oblongus
Famous for being one of the few freshwater fish that actively consumes Black Beard Algae (BBA). A torpedo-shaped, active bottom-to-midwater swimmer native to Southeast Asian streams. True Siamese Algae Eaters feature a distinct black horizontal stripe that extends all the way through the tail fin. As they mature, they can become lazy, preferring prepared foods over algae, and may occasionally chase other bottom dwellers.
Japanese Ricefish (Medaka)
Oryzias latipes
A hardy, small, and colorful fish native to East Asia. Extremely popular in the outdoor pond hobby and nano aquariums. They are 'amphidromous' (tolerant of salinity changes) and can survive a wide range of temperatures, making them excellent tub/pond fish. They are surface dwellers that look best when viewed from above (top-down).
