Tigerfish (Datnoid Fish)

The Tigerfish is a type of freshwater fish that is native to Southeast Asia. They are known for their distinctive appearance – with long, slender bodies and unique patterns of stripes and spots on their scales.

Datnoid fish are generally peaceful and can be kept with a variety of other fish species in a community tank – they can also be territorial and may become aggressive towards other fish if they feel threatened.

These fish are typically carnivorous and require a diet of live or frozen food, such as worms, insects, and small crustaceans. Datnoid fish are not commonly found in the pet trade, but they can make interesting and rewarding additions to a well-maintained aquarium for experienced aquarists.

Description of the Datnoid Fish

Young datnoid fish are small, usually only a few inches in length. They are known for their tiger-like stripes, which can vary in number depending on the species. They have a tall, slender body with a sharply slanted forehead and are colored with a combination of gold and white.

Due to their long lifespan, datnoid fish tend to grow slowly in their early years, reaching a foot in length around middle age. In optimal conditions, they can eventually grow to be 14 inches or longer, but this takes several years or more.

In the wild, datnoids can grow to be larger than 18 inches, but in captivity, they tend to be more manageable at around one foot in length. Some individuals may reach 14 inches, but this is rare. Datnoids can live for up to 10-15 years in captivity.


Tigerfish are known for their distinctive appearance, with elongated bodies and bright, colorful patterns. Datnioides have only 24 vertebrae. The hard rayed part of the dorsal fin has 12 fin rays, the far back sitting soft rayed 15 to 16. Together with the likewise far back sitting anal fin and the round caudal fin the impression of three caudal fins arises.

Some of the key characteristics of Datnioides fish include:

  1. Elongated bodies: Datnioides fish have slender, elongated bodies that are well-suited for predatory behavior. They have large heads and eyes, which help them locate and capture prey.
  2. Bright, colorful patterns: Many species of Datnioides fish are brightly colored, with distinctive markings and patterns on their bodies. These patterns can vary significantly among different species and may be used for communication or to help the fish blend in with their surroundings.
  3. Sharp teeth: Datnioides fish have sharp teeth that are used for tearing and ripping apart prey. These teeth are especially prominent in the upper jaw and are used to hold onto struggling prey.
  4. Aggressive behavior: Datnioides fish are known for their aggressive behavior, particularly when hunting or defending territory. They are known to attack and eat smaller fish, as well as crustaceans and other invertebrates.
  5. Adaptability: Datnioides fish are highly adaptable and can be found in a variety of aquatic habitats, including streams, rivers, and lakes. They are able to tolerate a wide range of water conditions and can thrive in both freshwater and brackish environments.

Types of Datnioides:

There are several different types of datnoids, each with their own unique features and characteristics. These include:

  • Siamese Tiger Fish or Wide Bar Datnoid: These are the most common types of datnoids, and they can be easily mistaken for Indonesian Tiger Fish due to their similar appearance. Siamese Tiger Fish have three main stripes on their body and two uneven stripes on the tail fin.
  • Indonesian Tiger Fish or Indonesian Datnoid: Indonesian Tiger Fish are similar to Siamese Tiger Fish, but they have three or four stripes on the body and two identical stripes on the tail fin.
  • Northern Thailand Tiger Fish or Thin Bar Datnoid: This species is found in the riverways of Northern Thailand and is known for its broad, straight stripes on the body. They may also have a yellowish hue to their bright golden color.
  • American Tiger Fish or Silver Tiger: Silver Tigers get their name from the silver tone on their body.
  • New Guinea Tiger Fish or New Guinea Datnoid: This variety is mostly found in the freshwaters of New Guinea and is easily identifiable by the wavy pattern of gold and black on their body.

Set up a Fishtank for Datnoides? Tank-Size, Water-quality,Interior and Substrate

Setting up an aquarium for Tigerfish, also known as Datnoids, can be a rewarding and enjoyable hobby. These beautiful and unique fish are native to Southeast Asia and require specific care to thrive in an aquarium setting. Here are some tips on how to set up an appropriate tank size, water quality, interior, and substrate for your Datnoides.

Tank Size:

The size of the tank you will need for your Datnoides will depend on the number of fish you plan to keep. As a general rule, it is recommended to provide at least 50 gallons of water per adult Tigerfish. These fish can grow up to 3 feet in length and are known to be quite active, so it is important to provide them with plenty of space to swim and explore.

Water Quality:

Maintaining good water quality is essential for the health and well-being of your Datnoides. These fish are native to Southeast Asia, where the water is typically soft and slightly acidic. To replicate this type of environment in your tank, it is important to maintain a consistent pH level between 6.5 and 7.5, as well as a total water hardness level between: 8 – 18°N (142.86 – 321.43ppm).

To maintain good water quality, it is important to regularly change the water and use a high-quality water softener. It is also a good idea to use a reliable filtration system and to test the water regularly to ensure that it is within the appropriate range for your Datnoides.


In terms of interior design, it is important to create a natural and visually appealing environment for your Datnoides. These fish are native to rivers and streams, so it is a good idea to mimic this type of habitat in your tank. Consider adding plants, rocks, and other decorations to create hiding spots and add visual interest. It is also important to provide your Datnoides with plenty of filtration to keep the water clean and healthy.


The substrate, or the material that lines the bottom of the tank, is an important consideration when setting up an aquarium for Tigerfish. These fish are known to dig and burrow, so it is a good idea to use a substrate that is not too abrasive or sharp. Sand or small gravel can work well, as long as it is smooth and free of any sharp edges.

In conclusion, setting up an aquarium for Tigerfish requires careful consideration of tank size, water quality, interior design, and substrate choice. By providing your fish with a spacious, healthy, and natural environment, you can create a happy home for your Datnoides to thrive in.

“What is the correct Diet for Datnioides?”

The species-appropriate feeding and nutrition of Datinoides do not pose any significant challenges, even to amateurs in the field of aquarists. Datinoides accept commercially available frozen, live and dry food. However, their favorite food is other smaller fish that they either actively chase or ambush.

What do Tigerfish eat in the wild?

In the wild, datnoids primarily feed on live prey such as worms, insects, small fish, crustaceans, and other small animals. They may also consume shrimp, crabs, and snails. While they may occasionally attack larger fish, this is rare, as they typically only hunt prey that is the same size or smaller than themselves.

Feeding Habits:

It is recommended to feed your datnoids once or twice a day, and to never give them more food than they can consume in one feeding. Wild-caught datnoids may be difficult to train to eat commercial fish foods, but young datnoids can be easily taught to accept a variety of commercial options such as pellets, meaty sticks, krill, or silversides. Live foods like feeder shrimp, fish, or bloodworms can also be offered.

Recommended Foods:

While Tigerfish do prefer live food, it can be challenging for home aquarium hobbyists to provide this consistently. It is possible to train them to accept frozen or pellet food over time, but due to their wild instincts, they will likely have a preference for live food. If you do choose to start with live food, be aware that it may be difficult to switch them to commercial, frozen, or pellet options later. It may be necessary to starve them or introduce competition in order to get them to eat.
