Dojo Loach (Weather Loach) Care Guide Summary
The Dojo Loach (Weather Loach), scientifically known as Misgurnus anguillicaudatus, belongs to the Loaches family group. Adults reach a maximum size of approximately 25 cm and have a eel body shape with a fast growth rate. Classified as peaceful, this species primarily occupies the bottom zone of the aquarium and produces a high level of biological waste.
To thrive, the Dojo Loach (Weather 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 10°C and 24°C, with a pH range of 6.5–8 and a general hardness of 5–15 dGH. A moderate water flow is preferred.
The Dojo Loach (Weather Loach) is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Standard Adult 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.
Dojo Loach (Weather Loach) Habitat Setup
When setting up an aquarium for the Dojo Loach (Weather 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. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper, expect substrate disturbance, so lightweight décor should be secured, and live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation.
Dojo Loach (Weather Loach) Compatibility Notes
Classified as peaceful, the Dojo Loach (Weather 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 and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.

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.
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.
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.
Discus
Symphysodon aequifasciatus
Known as the 'King of the Aquarium', Discus are stunning, heavily laterally-compressed cichlids. They are famous for their demanding husbandry, requiring high temperatures (28-32°C / 82-90°F), pristine water quality, and specialized diets. They are schooling fish that establish a strict pecking order and must be kept in groups to prevent intense bullying of a single weaker fish.
Fahaka Puffer
Tetraodon lineatus
A massive, highly intelligent, and extremely aggressive freshwater pufferfish native to the Nile, Senegal, and Niger rivers. Often referred to as 'water dogs' due to their owner recognition and begging behavior. They are strictly solitary pets that will relentlessly attack and kill any tank mates. They require a diet of hard-shelled invertebrates to keep their ever-growing teeth trimmed.
Platy
Xiphophorus maculatus
A quintessential community fish known for its durability and massive variety of colors. Native to Central America, Platies are livebearers, meaning they give birth to free-swimming fry. They are peaceful, active grazers that require hard, alkaline water to thrive. They are excellent for beginners but breed prolifically.
