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.

Dwarf Chain Loach Care Summary
The Dwarf Chain Loach, scientifically known as Ambastaia sidthimunki, belongs to the Loaches family group. Adults reach a maximum size of approximately 6 cm and have a fusiform body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the bottom and mid-level zones of the aquarium and produces a low level of biological waste.
To thrive, the Dwarf Chain Loach requires a freshwater only aquarium with a minimum volume of 75 litres and a tank length of at least 60 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 2–12 dGH. A moderate water flow is preferred. To replicate their natural habitat, the tank should include sand (sifters), smooth gravel (sensitive barbels), and plants - densely covered.
As a schooling species, Dwarf Chain Loach should be kept in groups of at least 6. Keepers should be aware that this species will eat snails. The Dwarf Chain Loach is typically available in one standard form.
Similar Species
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.
Honey Gourami
Trichogaster chuna
The smallest and most peaceful member of the Trichogaster genus. Ideally suited for planted nano aquariums. Unlike the aggressive Dwarf Gourami (*T. lalius*), Honey Gouramis are timid and gentle. True Honey Gouramis rarely exceed 5cm. Note: Many bright red fish sold as 'Red Honey' or 'Red Robin' are actually Thick-lipped Gouramis (*T. labiosa*), which grow larger.
Dwarf Pea Puffer
Carinotetraodon travancoricus
The Dwarf Pea Puffer is a tiny, fully freshwater pufferfish native to India. Despite their cute appearance, they are fierce micropredators and notorious fin-nippers. Modern husbandry standards strongly dictate they are highly social and must be kept in species-only shoals of 6 or more in heavily planted aquariums to disperse aggression and reduce stress. They require a steady diet of small snails and live/frozen foods.
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.
African Butterfly Cichlid
Anomalochromis thomasi
A peaceful, colorful dwarf cichlid from West Africa. Unlike many cichlids, it is plant-safe and generally suitable for community tanks. It is famous in the hobby as an efficient biological control for pest snails.
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.
