YoYo Loach (Botia Lohachata)

YoYo Loach Tank Setup, Caring and Breeding Profile

YoYo Loach

YoYo Loach

Yoyo Loach Introduction:

Beautifully patterned Yoyo loach fish gets its common name from the markings on its side that seem to spell out the word “yo-yo.”There are several other, closely related species that also go by that name but B. lohachata displays the word more clearly than the others.

It is also commonly called the Pakistan loach, but that just leads to confusion as it is used for several intricately patterned botias and the yoyo loach is not from Pakistan.

Tank Mates Analysis:

These fish are very fast moving and lively so they may cause stress among slow-moving tankmates. And while most get along well with other fish individuals have been known to find the long fins of some tankmates irresistible. Some botias may show aggression towards similarly shaped fishes when they are kept singly or in pairs. That is because they are highly social creatures with a relatively high intelligence.

Tank size & setup:

They require the social interaction of a group of 4 or more yoyo loaches to satisfy them. They are also extremely curious and quickly become stressed in a bare tank. Give them lots of places to explore like caves, clusters of stones, groves of plants or man-made decorations. But be careful! Yoyo loaches like to squeeze into tight areas and sharp decorations can injure them. A 30 gallon/ 115-liter tank is sufficient for a group.

Fish Size & Origin:

They are found in the waters of Nepal and India. Maximum supply you can get from these areas may be you can also get the price difference if you buy them from these areas.

Such Loaches can grow up to the size of 10 cm or 4 inches in size. This is the mature size the fish can gain in Lbs.

Optimum Temperature Range:

Does not require a heated aquarium but can tolerate up to 27°C/ 82°F.So there is no Specific Parameter in this regard.


Botias will eat anything from dried to live foods and from algae wafers to soft-leaved plants. The also will eat snails but not at a rate of clearing up an infestation for you.


Botias like clean well-oxygenated water. Sand or fine gravel is preferable as a substrate so as not to damage their barbels. And of course, lots of decors for them to explore. They are interesting, social fishes that make good residents for most community tanks. There are some exceptions though.

How to do Breeding?

These fish migrate up streams to spawn in nature. It has not occurred in captivity without the use of hormones.

Eightbarbel Rice Loach Tank Size

If you like Dojo Loaches, you will love the Eightbarbel Loach. They grow to less than half the length of dojos. Four or five could easily be kept in a 20 gallon/ 80liter tank.

Funny things they do?

If all the fish I currently own, these have become my favorite. I love how they leisurely swim through the water. They do not swim clumsily like many other loaches with wormlike bodies. Instead, their swimming method is more similar to other types of loaches like the Rainbow Shark.

They frequently can be seen just hovering in place just above the floor of the aquarium. I estimate that they spend less than 50 percent of their time on the bottom. They are capable of short jumps but I have never seen them try. I only know they can because I was floating a breeding box in their tank with Rice Fish fry (Oryzias latipes– a killifish native to the same waters as the loach) that I had hatched.

I came home from work with one loach in the breeding box and about half the fry gone. They are quite adept at eating fry. I have since removed the rice-fish as I want to continue breeding them but added a pair of guppies to their tank to provide the loaches will occasional opportunities to hunt young fish.

I will add a video of my fish in this section ( I apologize in advance for the shaky camera work and glare)


These are found in the lands of

  1. The Koreas
  2. Northern China
  3. Russia

Fish Size:

The fish size depends on the room, space and environment you are providing them and also food you are going to feed them. So the maximum fish size is 7cm/ 3inches  or sometimes maybe less.

Temperature Range:

Room temperature but can handle both higher and lower for a few months. Not any specified temperature had set for them.

What do they eat?

They have proven very easy to feed. They eat flakes, pellets, sinking cory tablets, and frozen and live food. They also eat small snails and small fish. At feeding time, they eat first from the water column, and sometimes from the surface, and only later combing the bottom for bits of food. Unlike dojos, they do not gulp air so they will never make a dash for the surface.

Housing Environment:

They inhabit slow-moving rivers, swamps, and irrigation ditches that are heavily overgrown with vegetation. They are often found around submerged branches. They do not bury themselves but avoid sharp gravel which could injure their whiskers.

Breeding Style:

After a period if cool temperatures, the Eightbarbel Loach may breed when the water temperature rises into the low/ mid-20s Celsius or low 70s Fahrenheit. Eggs are deposited in thickets of vegetation.

Reading through several blogs from native fish keepers in Korea, it is clear these fish have been bred in captivity. The genders difference is obvious when you see them side by side. Males have a dark strip, often faded and only visible from certain angles, while the females have a series of random spots.

White-Nosed Loach & Spotted White-Nosed Loach

Spotted White-Nosed Loach For Home Aquariums

When I went to Seoul this week to view the display of native Korean fish in aquariums, several species caught my eye as having potential in the global aquarium market.

Among them were the dozen or so species of elongated loaches. Most of them have beautiful markings but otherwise unremarkable colors. The two members of the genus Koreocobitis, however, sported eye-catching blotches of red of varying intensity.

In the first two photos are K. rotundicaudata showing color variation over a different substrate. The third picture is of K. naktongensis. These two fish are very closely related and until recently, were classified as the same species. However, the spotted white-nosed form inhabits only the southern Nakdong River in South Korea while the more common white-nosed version inhabits a broader ranger in the northern half of South Korea.

Tank Size

They are long fish and a group of them should be housed in a fifty gallon/ 180-liter tank. Because they inhabit just the lower portion of the tank, you could house them with any midwater fish that like flowing water and can tolerate room temperatures.


They are found in Endemic to South Korea waters. You can Found them there.

Fish Growth:

They can grow Up to 18cm / 8 inches if they are cured and cared properly in an effective way.

Temperature Levels:

No heater is needed. No, any temperature range is specified so you can keep them in room temperature or normal water temperature. It’s easy to keep them in the aquarium.


They adapt readily to sinking, prepared foods but should be given regular feedings of live or frozen foods such as bloodworms.


It is likely that these cousins can interbreed as their differences were caused by geological separation. They are called white-nosed loaches, despite clearly not having white noses, because of the light band that extends across the top of their heads nearly to the tip of their noses. They lay eggs in the substrate under stones. In nature, breeding in May and June.


Their tank should contain many stones and a substrate of sand or gravel. Take four smaller stones and arrange them so a large, flat stone can be laid atop them like a table. Secure the stone with aquarium safe sealer so it cannot shift and injure the fish.

The opening to beneath the stone should be only slightly higher than the height of the loach. They will spend most of their time underneath this structure and may even breed there.


The water should be well filtered with a good flow of water and extra oxygen added to the tank via an airstone. Be sure to cover the intake valve of the filter with a sponge or fine nylon mesh as. From a stocking. These Loaches have a tendency to enter the filter pipes.

DOJO LOACH (Misgurnus anguillicaudatus)

Dojo Loach – Best Care tips For Your Water Fish

DOJO LOACH (Misgurnus anguillicaudatus)

Dojo Loach (Misgurnus anguillicaudatus)

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.

Tank Size

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!


  1. Northeast Asia
  2. Siberia.

Length by Size:

They can fairly get 8-10inches / 20-28cm size but give them proper care as mentioned.

Temperature Tolerance:

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.
