Properties:Yoyo Loach is a fairly peaceful and sociable loach. The fish feels most comfortable in a group of conspecifics in spacious aquariums. They can also be kept well with other loaches, alien fish are mostly ignored by this loach. Net loaches are mainly crepuscular and nocturnal. A sex differentiation is only possible at the spawning point of adult females.
Aquarium:Yoyo Loach should not be kept under 100 cm in length in aquariums, because the animals love to swim. Sand or fine gravel should be used as the substrate; if several animals of this type are kept, the aquarium must be well structured with stones and roots.
Water quality:The Yoyo Loach is very adaptable to the pH value, so this can be in the range from 6.0 to 7.8, the water hardness around 4 to 20 ° dGH.
Temperature:The optimal temperature range for blue bass is 22 to 28 ° Celsius.
Food:The Yoyo Loaches can eat commercially available ornamental fish food without any problems. For a change, the menu may include frozen and live food more often.
Achievable size:The loach can be up to 18 cm long.

OriginNorth India, Pakistan, Nepal, Bangladesh
Natural habitatThe net loach lives in oxygen-rich and clear rivers that drain the Himalayas. There rather in calmer side sections with a moderate current. The juvenile net loaches live at a height of at least 300m above sea level. After sexual maturity, they migrate to much higher water bodies up to 1600 m.
SizeIn the aquarium the animals can be proven to be over 17 cm tall.
FeedIn nature mainly snails, insect larvae and growth. 
But young shoots of some aquatic plants are also eaten with pleasure. 
Strong live and frozen food should be fed regularly in the aquarium. 
Food tabs and flake food are also welcome. 
Regular feeding with green fodder and vegetables should also take place.
Aquarium requirementsLength: 120 cm
Content: From 150 liters
Lighting: Shady
Facility: Plants, hiding places
Water valuesTemperature: 24-30 ° C
PH value: 6th
Carbonate hardness: 5 ° dKH
Total hardness: 2-16 ° dGH
BehaviorYoyo Loaches (Botia almorhae) should be kept in larger groups of approx. 5 or more animals. In contrast to eel loaches, they are almost always together in a group. They are then just as playful as clown loaches.

They need many burrows in the aquarium with suitable water conditions. There should be a lot of roots in the tank that dig into the ground like fingers.
The lighting must be dimmed in places.
You should not house Yoyo Loaches with other loaches because of the size difference.
Loaches are pretty rough when it comes to food. They ted to eat in small chunks.
Yoyo Loaches nibble on aquatic plantsYoyo Loaches eat holes in echinodores. The planting has to be loach-friendly or you have to live with holes in the plants.
You should feed them food tablets with a high proportion of spirulina.
Yoyo Loaches eat other fishYoyo Loaches sometimes eat other animals out of boredom or frustration.
Reasons why net loaches eat other fish:

·       The aquarium is too small.
·       The aquarium setup is unsuitable for loaches.
·       The lighting of the aquarium is unsuitable for loaches.
·       The water in the aquarium is unsuitable for loaches.
·       The food is unsuitable for loaches.
AttitudeIn their natural habitats, the animals like to hide in cracks and crevices between the stones. In the aquarium this can be offered to you by means of stone structures or suitable tubes. Care should be taken to offer more such hiding places than there are animals in order to minimize the resulting aggression. For example, at least eight hiding places should be offered for five animals. At least five animals should be kept together.

Net loaches are good for community aquariums. However, care should be taken to ensure that their needs are taken into account. For the establishment of a biotope aquarium, for example, the less warmth-loving Malabar or Devariobarblings would be very suitable. They should not necessarily be kept together with bottom-dwelling fish such as armored catfish, which are inferior in feeding.
External physiologyThe scales of the Yoyo loach are extremely small and shine golden and silvery in young animals, and gray to yellow in adult animals. The net pattern shows itself in juvenile net loaches in its typical Ypsilon (YYY) shape in black. Hence the English name Yo-Yo Loach. In adult animals, the pattern changes into a labyrinth-like and unique pattern in shades of brown. Net loaches, like other loaches species, have a thorn under the eye that can be folded out for defense.
Gender differencesThe sexes can only be distinguished by the spawning approach of the females.
BreedingNot detected in the aquarium.

Yoyo Loach: Diseases and Infections

Big bellies in Yoyo Loaches


External symptoms
  • Stomach swollen
  • Bumps on the body


  • The belly swelling is caused by ascites.  Outwardly indistinguishable from ascites are the effects of an intestinal tear. A tear in the intestine can occur when a fish is injured while being caught. The mash then passes through the crack into the body cavity and inflates the fish.
  • Another cause of fat bellies can be intestinal flagellates.
  • More rarely, fat bellies are caused by hardening of the spawn. Such animals need to be watched closely when the bellies appear to be getting bigger.
  • Tumors
  • Constipation
  • Cysts

Uneven bulges on the fish’s body can be caused by constipation, cysts, or internal tumors.



Infectious ascites can usually only be cured in the early stages. This is another reason why it is essential to determine the actual cause of the disease. The treatment can only be successful with the quick and targeted use of remedies.

 There are some remedies available in stores that, if used in a timely manner, can help. Without eliminating the causes, that is to say, as a rule, improving the hallway conditions, no treatment will help.

The treatment can be supported by a salt treatment with 2 to 5 grams per liter of water. The exact salt dose depends on how much salt the fish can tolerate. 

The salt treatment supports osmosis regulation primarily through the skin so that some of the excess fluid can be released. At the same time, a salt bath has a vitalizing effect on the infected fish.

Intestinal flagellates

Intestinal flagellates can be treated with the following remedies. The main active ingredient contained is named in brackets.

  • Amtra medic 5 (2-amino-5-nitrothiazole)
  • HS Spirocell
  • Hexa-Ex ([2-Amino-5-nitrothiazole)
  • JBL Spirohexol (2-Amino-5-nitrothiazole)
  • Price Coly (garlic , wild mallow, tansy, worm fern)
  • Zoomedica Frickinger (azole | 2-amino-5-nitrothiazole)
  • Sera med Professional Flagellol
Spawn hardening

Before treatment, it must be ensured that the normal spawning time is clearly exceeded. Ideally, the fish hangs in a net approx. 1 cm below the water surface during treatment.

Alternatively, the fish is placed in a damp cloth. A thumb and index finger are very carefully placed on both sides just in front of the anus of the fish. Then you gently stroke towards the anal fin with very gentle pressure.

Under no circumstances should it be painted with strong pressure. It is also not allowed to stroke the whole body. Otherwise fatal ruptures of the spleen or liver can result. If the hardening cannot be removed with a very light brush, you have to stop because the risk of injury is too great.

The eggs can easily fall into the aquarium and are good fish food. In any case, fingers must be wet when painting. In no case should the fingers be too dry, as this can lead to injuries.


Treatment of tumors is usually not possible.

Since tumors are incurable, Yoyo Loaches should be killed if they have tumors. This is especially true if the tumor grows in the mouth area and the fish are in danger of starving.

Fish with lymphocystis should be isolated. As soon as bacterial or fungal infections develop, they should be treated.


If no clear cause can be determined, the temperature can be slowly increased to 30 ° if the fish can tolerate this temperature. The increase in temperature stimulates the metabolism and the constipation can possibly be released.

If the affected fish are still eating, laxatives can be given with the food. To do this, you soak some flakes of dry food in rhubarb or castor oil. Alternatively, Epsom salt (magnesium sulfate) is mixed into the food or approx. 12 to 15 mg per 100 liters of water are added to the aquarium. A few drops of garlic in the food are also recommended to stimulate digestion. Feeding water fleas can also help.

A very light massage can also help, in which you carefully loosen the blockage with very light pressure.

You can prevent constipation by feeding natural yoghurt or low-fat quark. To do this, add some natural yoghurt or low-fat quark to the aquarium about once a week. Only small amounts should be given at once, as many small flakes can easily form in the water.

Lymphocystis itself is incurable. Since the nodules can fall off as they develop and thus disappear, the impression can arise that the disease has been cured. Viruses are usually still present in the aquarium.

There is only the possibility of preventing injuries as much as possible and avoiding stress factors that weaken the immune system.


There is no effective treatment for cysts. When the cyst of the lemon tetra pictured above had reached the size shown in the bottom picture, I put the tetra in a bath with Tetra General Tonic. After that, the thickening gradually decreased. It has not disappeared completely, but it is barely visible. Whether this is a coincidence or a result of the treatment is just as unclear as the question of whether it is really a cyst.
