You could argue that this fish belongs among the coldwater species that I post about on Sundays, but the Dojo Loach has become so firmly established in the aquarium trade that I prefer to write about it on Monday, the day I write about common fish store finds and easy to care for fish. It is certainly easy to care and is very adaptable.
Nature of Dojos:
In fact, it is so adaptable that it now an invasive species in many temperate countries as well as the mountainous regions of some tropical areas. However, the dojo loach is NOT a tropical fish.
Important Note: Another mistake that people often make is to assume the loach can be treated as a scavenger. While it will eat leftover flake food, dojos– like most loaches– are predators of small invertebrates and fish fry. They are not to be trusted with your baby guppies!

On rainy days or humid nights, an outdoor dojo can decide to go for a walk and leave the confines of the pond to see what other waterways are nearby.
Even inside, your dojo may appear to become very agitated or excited when a storm approaches. Their sensitivity to changes in atmospheric pressure earned them the alternate common name of Weather Loach.
The dojos in stores are often gold or albino. The natural coloration is various shades of brown and olive speckles, but it may appear lighter over a white substrate.
Dojos can get fairly large. They should not be kept in less than a 30 gallon/ 110-liter tank, but do not keep them in your outdoor ponds!

Length by Size:
They can fairly get 8-10inches / 20-28cm size but give them proper care as mentioned.
They can tolerate 5-23°C/ 41-74°F but the extreme lows and highs should be seasonal. Although it can live for quite a while at temperatures suitable for tropical fish, keeping them at high temps shortens their lifespan dramatically.
Diet & Food:
Give and feed them with Bloodworms and brine shrimp..live or frozen. Also flake foods, pellets, and anything else that fits in their mouths.
The most important feature of their tank is the substrate. Fine sand, sunken leaves, or mud are ideal. These fish love to bury themselves in the substrate with only their head showing. The filtration should not create too strong a current and be careful that the intake tube to the filter is securely covered so the loaches cannot enter. Provide your loaches with shaded areas or plant cover as they don’t like bright lights.
How to do Breeding?
Females scatter eggs in thickets of plants. Probably requires seasonal temperature fluctuations to induce spawning.
