Taxonomy
- Family: Datnioididae
- Genus: Datnioides
- Scientific name: Datnioides microlepis
- Common synonym: Indonesian Tigerfish
Habitat
FishBase records the species from the Chao Phraya and Mekong basins of mainland Southeast Asia, the Kapuas basin of Borneo and the Musi basin of Sumatra; Wikipedia emphasises Sumatra and Kalimantan. It occurs in large lowland rivers, lakes and reservoirs with submerged branches and flooded forests, sometimes entering brackish water, and is protected in Thailand.
Tank requirements
- Minimum tank volume: 600 L
- Temperature: 24-28 °C (75-82 °F)
- pH: 6.5-7.5
- GH: 5-15 °dGH
- Lifespan: 10-15 years
- Water type: freshwater
Diet
Adults are predatory, consuming crustaceans, smaller fishes, annelids and insects, while juveniles feed on zooplankton. In the aquarium it takes meaty and live foods, fed roughly every two days.
Compatibility
Adults are solitary and aggressive toward conspecifics, whereas juveniles may shoal. Suitable companions are large robust fish such as arowana and big catfish; small fish should be avoided as prey.
Breeding
In the Kapuas River the species is reported by fishers to spawn in April and May.
Conservation status
IUCN Red List: Least Concern, though overfishing and pollution threaten some populations.
Indo Tiger Datnoid Breeding Guide
Overview
The Indo tiger datnoid is a large predatory fish endemic to Sumatra and Kalimantan in Indonesia. Wikipedia reports a maximum published total length of 65 cm, making it the largest species of Datnioides, and lists it as IUCN Least Concern, though overfishing and pollution threaten some populations. It lives in large lowland rivers, sometimes entering brackish water, and favours areas with submerged branches and flooded forest.
Spawning Behavior & Trigger
Documented reproductive information is limited to the wild. In the Kapuas River, local fishermen have observed that this species spawns in April and May. No captive spawning, courtship behaviour, egg data or fry-rearing records are available in the reviewed sources, so no aquarium breeding protocol can be given.
