Zebra Loach

Botia striata

Loaches

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.

Standard

The standard and only commercially available form of the Zebra Loach. Must be kept in groups of at least 5 (preferably more) to prevent them from becoming withdrawn, stressed, or exhibiting unnatural aggression. A sandy substrate is critical to prevent their delicate sensory barbels from wearing away.

Zebra Loach Care Guide Summary

The Zebra Loach, scientifically known as Botia striata, belongs to the Loaches family group. Adults reach a maximum size of approximately 9 cm and have a fusiform 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 Zebra 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 21°C and 26°C, with a pH range of 67.5 and a general hardness of 210 dGH. A moderate water flow is preferred.

The Zebra Loach is a rewarding species to keep, provided its core environmental needs are met. The Zebra Loach is typically available in one standard form.

Zebra Loach Habitat Setup

When setting up an aquarium for the Zebra 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.

Zebra Loach Compatibility Notes

Classified as peaceful, the Zebra Loach is a social species that requires the company of its own kind to thrive. When choosing tankmates, snails will be treated as food rather than tankmates. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.

Yoyo Loach

Botia almorhae

Loaches
15 cm Mostly Peaceful

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.

Kuhli Loach

Pangio kuhlii

Loaches
10 cm Peaceful

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.

Zebra Danio

Danio rerio

Cyprinids
5 cm Mostly Peaceful

One of the most robust and active aquarium fish available. Native to South Asia, they are a model organism in science due to their genetics. They are extremely active top-level swimmers that must be kept in schools to prevent stress and fin-nipping. They prefer cooler, oxygen-rich water with a current.

Dwarf Chain Loach

Ambastaia sidthimunki

Loaches
6 cm Peaceful

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.

Clown Loach

Chromobotia macracanthus

Loaches
30 cm Peaceful

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.
