The Mojo Dogo Loach (Misgurnus dabryanus), more widely known as the Large-Scale Loach and also sold in the aquarium trade as the Mojo Dojo Loach, is an unusual East Asian weather-loach relative with an elongated body, sensitive barbels, curious personality, and remarkable ability to breathe atmospheric air through a specialized portion of its intestine.
Its coloration is highly variable and may include combinations of:
covered with irregular:
The species is naturally adapted to cooler, slow-moving freshwater environments, including muddy rivers, ponds, irrigation channels, rice-field habitats, and other low-gradient waters.
One of its most remarkable adaptations is its ability to:
This allows the fish to survive periods of low dissolved oxygen far better than most aquarium species.
That impressive survival ability also makes responsible ownership especially important because the species has demonstrated the potential to survive outside aquariums and establish non-native populations.

The taxonomy of East Asian weather loaches has been complicated for many years.
This fish has been called:
by different scientific authorities.
Even recent research continues to use:

Therefore, including all three names helps customers understand exactly which fish is being sold.
The Large-Scale Loach resembles the familiar:
but they are different species.
Important identifying characteristics of M. dabryanus include:
One practical distinction is:
commonly shows:
However, these species can still be difficult to distinguish visually.
Large-Scale Loaches have frequently been imported or sold as:
because of their very similar body structure.
Scientific studies have even discovered populations originally identified as M. anguillicaudatus that genetic testing later proved were:
Therefore, supplier identity and locality information are valuable.
Typical coloration ranges through:

The fish has an elongated:

Despite the eel-like appearance, it is a true loach in the family:
The mouth is surrounded by sensitive:

Large-Scale Loaches naturally occupy habitats including:
They are especially associated with:
and relatively calm water.
This species should not be treated like a:

An opening that appears too small may still be investigated by a determined loach.
One of the most fascinating characteristics of this species is:
The fish can swim rapidly to the surface and:
Scientific research has demonstrated that the:
is specialized for gas exchange.
The tissue is:
This functions as an:
It is normal to occasionally see the fish:
This does not automatically mean something is wrong.
However:
This species can tolerate low oxygen better than many aquarium fish.
That does not mean it should be intentionally maintained in:
Always provide:
Scientific researchers have documented a curious behavior in this species known as:
Individuals may occasionally float near the surface briefly, particularly at night.
This behavior appears connected with:
Short episodes are not necessarily a sign of disease.
Occasional controlled floating can occur naturally.
However, persistent:
should always be investigated as a potential health problem.
Your older page recommends:
That is too warm as a normal long-term recommendation.
FishBase gives a documented environmental range of:
This is therefore:
rather than a warm tropical species.
For normal aquarium maintenance, I would recommend approximately:
with:
being a comfortable middle range for many setups.
Avoid keeping the fish continuously above:
unless there is a specific short-term reason.
The species tolerates cool temperatures, but aquarium fish should still be protected from:
Stability remains important.
A practical long-term range is:
Because of its cooler temperature preference, Largescale Loaches should generally not be permanently combined with tropical species requiring:
Examples include many:
Choose tankmates based on overlapping temperature requirements.
Your old page lists:
as the approximate adult maximum.
FishBase currently documents a maximum of:

Therefore, I would use:
for responsible adult planning.
Although the fish is relatively slender, it is:
For long-term care:
is a good recommendation.
For several adults:
with a long aquarium footprint is preferred.
This species spends a great deal of time:
A:
is therefore much more useful than a short, tall aquarium.
Large-Scale Loaches are generally:
They can be maintained singly, but social interaction is natural for weather-type loaches.
When space allows, keeping several compatible individuals can result in:
A group of nearly 9-inch loaches requires substantial room.
Do not compensate for a small aquarium simply by adding more fish because the species is social.
Aquarium size must increase with group size.
This is generally a:
It does not normally hunt or attack healthy tankmates.
Its constant foraging can make it:
but not normally aggressive.
Good tankmates include peaceful species that tolerate similar:
Avoid mixing solely based on temperament.
Temperature compatibility is equally important.
Although peaceful, this is still an:

This is feeding behavior rather than aggression.
Scientific ecological studies describe this species as an:
Its natural diet includes:
Suitable aquarium foods include:
Quality prepared foods should also be offered.
Suitable choices include:
The natural diet also includes:
so a completely meat-only diet is unnecessary.
A balanced omnivorous feeding program is best.
For long-term health, offer:

Scientific risk assessments report that Large-Scale Loaches can become sexually mature at approximately:
with maturity reported in fish roughly:
under suitable conditions.
This reproductive capability is one reason responsible no-release practices are important.
Your older page described a very broad range including:
Current taxonomic sources are more conservative.
The current Catalog of Fishes recognizes the native distribution primarily as:
The species was originally described from the:
and occurs across substantial portions of:
Native populations are also recognized from:
The species has been moved extensively for:
As a result, some populations historically considered native may actually represent:
This is another reason distribution information varies among references.
Misgurnus dabryanus is currently assessed as:

The current assessment dates to:
This section is especially important for this fish.
Large-Scale Loaches have been introduced outside their native range through:
Genetic testing confirmed:

Fish collected there had originally been mistaken for the Oriental Weather Loach.
Aquarium release was identified as a suspected introduction pathway.
A U.S. Fish & Wildlife Service ecological risk assessment found the species has:

Weather loaches and other nonnative fishes are regulated differently from state to state.
Some jurisdictions specifically restrict certain:
species or weather loaches.
Because identification between closely related species can also be difficult:
This species combines:

For this product, I recommend:
Taxonomic authorities do not all currently use the same genus for this fish.
Recent scientific literature and U.S. government resources may continue to use:
while the current Eschmeyer Catalog of Fishes and FishBase recognize:
The two names in this context refer to the same Large-Scale Loach.
The Large-Scale Loach has been transported internationally through the:
and has established or been detected outside its native range.
The species possesses several adaptations that can increase survival after accidental or deliberate release, including:
Live fish are professionally packed for safe transport.
Shipping availability depends on:
Weather and destination restrictions are especially important for this species because nonnative loaches may be regulated differently between states.
