Datnoid care (7 interesting facts)

In this article of “Datnoid care,” we will cover the important setups of the aquarium to give the datnoid fish better care. We will also discuss the essential food for datnoid care and protection from diseases.

What are datnoids?

You might have visited a pet store and you might have caught sight of an angular looking striking predator in a fish tank with some fishes. They have bold stripes and are predators in nature. These fishes are called datnoids. Datnoid care is important to keep them healthy in your aquarium.

Datnoids belong to the family Datnioides and they are little unusual than any other fish. They are found in Southeast Asia, Indonesia and New Guinea. Datnoid care is not very tough.

One of the species is New Guinea Tiger Perch which live in brackish swamps. They can live in freshwater but not for a long time and to thrive they need to return to the brackish swamp.

All of the fishes used for trading are purely freshwater fishes and the most common of two are Indonesian Tiger Fish (Datnioides Microlepis) and Siamese Tiger Fish (Datnioides Pulcher).

The Indonesian tiger fish is found in Malay peninsula and Sumatra while the Siamese tiger fish is found in Chao Phraya river basins and the Mekong. They are freshwater datnoids.

These fishes are becoming more popular because they are used as food fish in Indonesia and Asian markets. People love to eat these fishes in Indonesia and different parts of Asia. They are thick-bodied fishes.

Datnoid care

Now we will dive into the details of datnoid care.


They are predators and they feed on other fishes. You can raise them on pellets and flakes but they do not do well with them. You can give them this food but only when you run out of meat and can’t buy it.

The best food for datnoid fishes is freshly chopped seafood like shrimp, clams and fish. They do well with this food. You can give them chicken breast and terrestrial protein sticks. 

Most of the fishes have a terrible environment in the fish tank because their owners do not pay attention to them. We will recommend you to use a fish tank that is free of any parasites like worms, blood-borne parasites and ich. The best choice is the quarantine tanks.

You should give your datnoid fish supplements along with thawed or live fish so that the datnoids have a strong immune system and it protects them from any kind of infection.

You can feed them by hand once they are trained. They have excellent sucking ability and can suck food from your hand from a distance, in this way they do not nip your fingers.

Datnoids are fed twice when they are juvenile and feed once when they are adults. They have high metabolism and demand for high temperature. This ability ensures that you can feed them many times a day without getting fat.

The choice of food is an important factor in datnoid care and protects them from various diseases.

Size of a datnoid fish tank

You need a large tank to keep these predators. Since they have a fast metabolism so they excrete a large amount of waste. Providing them with a large tank is a challenge.

They can grow up to 16 inches and 125 gallons of water is not enough for them. Atleast they should have 180+ gallons of water. Juveniles are easily kept in smaller tanks but when they are adult they need a large tank.

A 55 to 75-gallon fish tank can give space to a few young Siamese Tiger Fish as they can easily escape from the dominant fishes in the tank as they can be territorial towards other fishes.

Size of the tank has a large impact on datnoid care.


Datnoids are peaceful yet predatory in nature. You need to choose wisely the tank mates for your datnoid fish.

If you place a Tiger Barb in the tank it would be good until your datnoid fish grows to 5 to 6 inches. When the datnoid fish grows to 5 to 6 inches the tiger barb will become their lunch.

They have a mouth, which have enough space and are projectile. They can swallow their tank mates when they are hungry enough. They have similar eating habits like American largemouth bass.

Following are some best tank mates for your datnoid fish:

  • The first one is large cichlids, they are rough in nature but the species like Oscars and Jack Dempseys are good-tempered and can live with your datnoid friend peacefully.
  • The second one is Arowanas, These fishes are a perfect match for your datnoid fish. Both of the fishes have similar habits and they are found together in nature. Both enjoy each other’s company and can grow fast.
  • The third one is large catfish. The catfish category includes predators like red-tail catfish and big vegetarians like Plecostomus. If your fish is big enough to survive and is armoured then you can place these fishes in the tank.
  • The fourth one is the Stingrays. They need the best water quality to survive. You need to make sure that these fish are fed before your datnoid fish eat all the food in the tank. They are digging predators and can eat your datnoid fish.
  • The fifth one is Silver Dollars and Tinfoil Barbs, They are non-predatory fishes and are excellent to place in the tank having datnoids, Arowanas and other hunters.
  • The sixth one is Spiny Eels, they are mostly nocturnal and are found in southeast Asia. They are big and other fishes can’t eat spiny eels. They feed on small meaty creatures like small fishes and worms.
  • The last one is other datnoid fishes, if you keep smaller groups they are not that nasty. But when you keep a group of 5 or more in the tank, they will end up feeding on each other.

It is very important to choose the tank mates wisely and is an important factor in datnoid care

Decorations and plants

You need a lot of space to keep these active fishes. Most of the aquarists keep them in empty tanks because it gives them enough space to move. It is easier to clean empty tanks because the faeces and other debris can be seen floating in the clean water tank.

We are strong supporters of providing pets with the best natural environment. If you want to buy a fish tank for your datnoid fishes, you need to buy a large one so that you can place plants, rocks and driftwood to give them a nice, pleasant and natural environment.

If you keep your fish in an empty fish tank, this would place stress on them as it is not like their natural environment.

Datnoid fishes are easy with plants around. They are not like cichlids who dig in the fish tank leaving plants alone. They are happy in the natural environment of the marine land.

Water conditions for datnoid care

Water conditions are important for datnoid care because most diseases are spread from water if the water is not clean.

When you buy a fish you need to make sure what species of datnoid fish is this. Do not rely on the pet store owner information as they are often misleading. Most pet store owners say that these fish are either brackish or freshwater. One of the perfect examples is silver datnoid.

They are often sold under the name of Siamese Tiger fish in the market. They do well in freshwater until a wound appears and they are soon dead.

Brackish datnoid need salt for their survival. Freshwater datnoid do need a touch of aquarium salt to boost their immunity as it grows a healthy slime coat on their body. It is said that freshwater species should be kept in freshwater and brackish species should be kept in saline water.

It is very rare that you fully recognize a freshwater species of datnoid until they are full-grown and become adults.

The brackish species of datnoid are easily recognized by changing the environment of the fish and see its behaviour in that particular water.

You should have a proper waste disposal system in the tank for Siamese Tiger fish and their tank mates. You can use a canister filter like that of Fluval FX6 for your giant aquarium when you do not want to change the water multiple times weekly.

They are equatorial fishes and they should be kept in higher temperatures ranging from 78 to 84 degrees Fahrenheit.

They are sensitive to skin infections and are susceptible to ich when kept in a low-temperature environment. They are also prone to fungal infection due to the spikes in nitrites, nitrates and ammonia.

Datnoids can tolerate some nitrates and ammonia but as they produce a lot of waste they cannot survive if the substances build up in the tank.

Most of the southeast Asian fishes survive in an acidic environment. Like that of other fishes datnoid also survive in pH ranging from 6.5 to 7.5. The pH range is from slightly acidic to slightly basic.

They live in the mouth of rivers where the ocean saltwater modifies their environment into salty and alkaline in nature.
