Tiger Datnoids

The Tiger Datnoid, also known as the Indonesian Tiger Fish or Datnoid, is a strikingly patterned freshwater fish prized by aquarium enthusiasts. This species, native to Southeast Asia, particularly in the rivers and estuaries of Indonesia, Thailand, and Malaysia, is known for its bold, tiger-like stripes and predatory nature.

Tiger Datnoids are easily recognized by their distinct, bold black vertical stripes set against a golden or silver background. These stripes resemble a tiger’s coat, giving the fish its name. The number and intensity of the stripes can vary among individuals, with younger fish displaying more vivid patterns. As they mature, their colors may darken. Tiger Datnoids can grow up to 14-16 inches (35-40 cm) in captivity, making them a substantial addition to large aquariums.

Tiger Datnoids are predatory and somewhat territorial. While not highly aggressive, they will actively hunt smaller fish, so they should be kept with similarly sized or larger tank mates. They are relatively peaceful with other large, non-aggressive fish but need plenty of space to establish territories. They are also known for being somewhat shy, often hiding among plants or rocks, especially when feeling threatened.

In the wild, Tiger Datnoids are carnivorous, feeding on smaller fish, crustaceans, and insects. In captivity, they thrive on a diet of:

• Live or frozen foods such as shrimp, small fish, and bloodworms
• Pellets designed for carnivorous fish
• Occasional meaty treats like pieces of fish or prawn A varied diet is important to keep them healthy and maintain their vibrant colors.

• Tank Size: Tiger Datnoids require a large tank due to their size and active nature, with a minimum of 150 gallons for a single adult. For community setups, even larger tanks are needed.
• Water Conditions: They prefer warm, slightly brackish water with temperatures between 75-82°F (24-28°C) and a pH range of 6.5-7.5. Although they can tolerate freshwater, slight salinity mimics their natural habitat and can be beneficial for long-term health.
• Tank Setup: The tank should be furnished with plenty of hiding spots such as driftwood, rocks, and caves. As they can be shy, providing cover helps reduce stress. Additionally, a strong filtration system is essential due to their carnivorous diet and waste production.

Tiger Datnoids should be housed with larger, peaceful species that can defend themselves. Suitable tank mates might include large catfish, arowanas, bichirs, or other sizable, non-aggressive fish. Avoid housing them with small fish, as they may be seen as prey.

Breeding Tiger Datnoids in captivity is extremely rare and difficult due to their size, territorial nature, and specific environmental needs. They are more commonly found in the wild or sourced from breeders.

With proper care, Tiger Datnoids can live for 10-15 years in captivity, making them a long-term commitment for dedicated fishkeepers.

This large, beautifully striped fish is a centerpiece for large, carefully managed aquariums. They require a bit of experience and attention but are rewarding for enthusiasts who enjoy their impressive size, bold patterns, and predatory behavior.
