This happens when they have ample space to grow. If you want to breed a fish longer than 6 inches, put them in a big tank with more than 55 gallons of water.

In the wild, the fish can grow up to 12 inches. This generally happens in ponds. However, it can happen in the aquarium if proper care, nutrition, and enough space are given to the fish.

Natural Habitat and Origin

Weather Loach, also known as Dojo, or Pond Loaches, is native to Asian countries like Japan, Korea, North Vietnam, South Korea, and Siberia. The fish is an inhabitant of slow-moving shallow water bodies. The water bodies in which they are mostly found is in pond, streams, bogs, and rivers. They ideally live in water with a thick amount of vegetation and muddy substrates. 

These fishes have adapted to the change in habitats where the water level is variable. The fishes can gulp air from the surface of the water where the oxygen level is depleted. They can even survive after jumping out from the water for a more extended period than other fishes. These fishes feed on small aquatic creatures, insect larvae, small crustaceans, and worms.

Tank Shape for Dojo Loach

The ideal tank shape for dojo loach is curved at the bottom. They like to move around in circles and dig deep in the bottom, so curved edges in the bottom are better for them. 

Substrate

The loaches are excellent diggers. They invest most of their time in searching for scraps of food. We would recommend you choose fine sand for the substrate. It helps them to get the right environment to dig with a pointed head. They like to explore and bury themselves in the bottom of the tank. So, go for anything soft, don’t go for gravel or pebbles or anything with sharp ends as they can quickly get a cut.

Filter Type

Filtration and oxygenation are also crucial parts of decorating the fish tank. The weather loaches prefer moderate flow, so you can achieve it by putting a filtration machine underneath the gravel. Another method is to use air stones. The air stones are easy to put and clean so that you can keep the fish tank maintained.

Water Temperature

The idea water temperature for Dojo Loach is 50-82degree Fahrenheit. However, you should aim for 65- 75 degrees Fahrenheit.

Ph Balance

The perfect water pH level for Dojo Loach is pH 6.0-8.0. Therefore, a little acidic level of water is not harmful, but it should not exceed the level of 8.2.

Water Flow Rate

Dojo Loach survives at a slow water flow rate. They are mostly found in ponds and rivers where the water flows at a slower pace compared to oceans. So. to give them the right environment in the tank, put the water flow at a slower rate. 

Water Hardness

The hardness of the water should fall between 5-12 dKH. The water should be fresh at the right temperature to breed and get good care. 

Dojo Loach Tank Landscape

When you welcome a new life into your home, start by giving them the same environment they are comfortable with. Dojo loaches enjoy most when they are in an environment that replicates their natural habitat. So put some driftwood, twisted roots, caves, and smooth stones.

Dojo Loaches tend to hide whenever they feel threatened, so caves are an appropriate decoration for them as they can hide from other fishes when they feel scared. 

Aquarists mostly prefer pieces of large driftwood and plants. Put it well in the substrate. You can even use soft pebbles to secure them, so they won’t get uprooted when they dig. 

Best Plants for Dojo Loach to Keep in Tank:

Worst Plant for Dojo Loach to Keep in Tank:

Best Diet for Dojo Loach

shrimps

Dojo Loach is easy to feed as they are omnivores and primarily feed on algae and organic matter. However, they don’t get these in fish tanks, so the onus is on you to provide them a well-balanced diet. It is best to provide them a variety of frozen, dried, and living foods. The food includes worms such as earthworms or bloodworms, shrimps, and small crustaceans.

If you are not sure if your fish are getting enough food as they scavenge food from the bottom, you can provide them liquid-based food, which is a turkey baster. Alternatively, you use tongs to put the food in the bottom of the aquarium to ensure they are getting feed properly. Another great choice is to feed them by sinking pallets. These are easy to put in the tank and meet their dietary needs. 

To ensure they are not nutrient deficient, you can supplement the dry food with frozen or live food like insect larvae or tubifex worms. Pond loaches get attached to the owner easily, so they like to be fed by hand sometimes. 

How Often Should You Feed Dojo Loach? 

We recommend you put food at various times in a day instead of giving them all at once. The interval of feeding the fish should be 3 to 4 hours. The best sustenance food type is a blend of plants and proteins. For the additional requirement to give better health to the fish, put some animal protein. It helps in coloring the fish and healthy growth. 

Behavior And Temperament

Dojo Loaches are relatively peaceful fishes, and they don’t cause trouble to other fishes. They tend to hide when they feel threatened to stay in the open. However, these fishes are pretty social and playful when they are in large groups. 

One of the best things about petting a Dojo Loach is they are friendly with humans. They respond to human contact, and when they start feeling safe, they will get used to you. So, if you take good care of your fish, they will feel comfortable getting feed by your hand, and they will even allow you to touch them.

But, as we have mentioned earlier, they are escape artists. You cannot confine them into one place. As a result, they will always find a space from where they can escape. So, if you find your fish one day on the floor, don’t get scared they can survive out of the water as they gulp oxygen from the atmosphere, put them back securely in the tank. So, if you are bringing Dojo Loaches, make sure you have taken enough measures to avoid this.

Are Dojo Loach Lone or Societal in Nature?

Dojo Loach is a social fish, and it needs other fish to feel safe around. So, when they are kept with other fishes, they like to come around in a day from their holes and make pyramids. It is so visually pleasing that you can spend an entire day watching them make one. 

However, if you put them alone in the fish tank, they will hardly come out of their holes and spend most of the time lying on the sand bed. So, you can keep at least two-three fishes with them to make them feel safe. They adjust quickly in the tank when they are not alone.

Tank Mates

One of the essential things you should consider while bringing a Dojo Loach is not putting them alone. They are social fish, so that you can fill the tank with non-aggressive fish. The weather loaches are bottom fishes, which means when you are looking for tank mates, look for fish that can occupy other parts of the aquarium like the middle or the top. Some of the tank mates for the fish are:

Ideal Tank Mates

  • Zebra danio (Danio rerio): Another fish you must consider as tank mates for dojo loaches or pond loach is Zebra Danio. They are mid-water and upper-water swimmers so that they won’t share the space with the dojo loach. The optimal temperature for keeping these fish is 65-75 degrees Fahrenheit. Moreover, they are very small.
  • White cloud mountain minnow: These look similar to Zebra danios and the ideal temperature to keep them is 60-72 degrees Fahrenheit. These fishes are even smaller compared to Zebra danios and have a length of only 1.5 inches which is 2.5 cm. However, it can grow up to 2.5 inches. 
  • Paradise Fish: If you are looking for the perfect pair of dojo loach, then look no more and get paradise fish. It is an ornate version of gourami fish. These fishes grow up to 2-4 inches. The paradise fish is aggressive compared to other fishes listed in this article now. 
  • Dojo Loach: Many aquarium hobbyists claim that Dojo Loach performs best when they are in a group. So, to make them feel safe in the tank, you should have at least three fishes so they can be closer to similar fish. 

Bad Tank Mates

  • Redtail shark: Redtail sharks are great to look at due to their colorful color, but they like to investigate every nook of the aquarium, so keeping them with Dojo loach is not a good idea. They will feel threatened.
  • Flowerhorn Cichlid: They are native to SouthEast Asia. Flowerhorns are aggressive, and they are significant. So, it is not an ideal choice for small aquariums.
  • Bucktooth tetra: They have a shimmery texture and add shine to your aquarium, but they are notorious little creatures. They like to peel off scales of other fishes and attack them for no reason.

While buying a fish, make sure the other fishes match the water temperature requirement of dojo loach and have similar food habits. Moreover, give them the right tank so every species can easily fit in a tank and have ample space to move around. Finally, the filtration and oxygenation should be in the right place. 

Breeding:

Dojo loaches lay eggs to reproduce. The females lay eggs, and they can lay from 100-150 eggs at a time. The eggs are 1.7-1.9mm in diameter and are brownish. Although they can’t be bored in the home tank, they are bred in the wild or farms.

Breeding Level: 

Hard

Sexual Dimorphism

It is easy to distinguish males due to their thick pectoral fins and fatty tissue. 

Common Diseases and Their Treatments

Ich

This happens quite often in dojo loaches. This is also called white spot disease, as white spots are caused over the body due to free-swimming aquatic parasites. The parasite is called Ichthyophthirius multifiliis. You can see the symptoms of a change in the behavior of the fish. They tend to flick or rub their bodies against any objects in the tank. 

It is easily treated. Raise the temperature of the water to 82 degrees Fahrenheit for three days continuously and treat the water with medication to cure the itch.

Bacterial Infection

This happens due to internal parasites. The weight declines suddenly, and it stops eating. It can be treated with antiparasitic medication.

Flukes

These are a parasite that gets attached to the gills or body of the fish. You can quickly identify this when the fish with flukes always rub against any solid object. To avoid this, treat the water with antiseptic medication.
