The Siamese tigerfish (Datnioides pulcher), also known as the Siamese tiger perch, is a critically endangered Asian fish native to the Chao Phraya, Mae Klong and Mekong basins.[1] It has vertical yellow and black stripes running the length of its body. The dorsal fin has a spiny appearance.[2] Siamese tigerfish grow to 40 cm (16 in) in standard length.[3]

The many species within Datnioides are quite commonly confused. Datnioides pulcher is the Siamese tigerfish, or wide-bar datnoid. Datnioides microlepis is the Indonesian tiger datnoid. Datnioides polota is the silver datnoid.

In the aquarium[edit]

It prefers a pH of 7.6–8.0, and a temperature of 22–26 °C (72–79 °F). The Siamese tigerfish is predatory and will eat smaller fish, various live foods, and frozen foods. Many hobbyists pellet-train their datnoids to reduce the risk of disease and parasites from live food. Captive ones are generally smaller than their wild counterparts, though may still require a large aquarium.[2]

Conservation status[edit]

D. pulcher is protected in Thailand, and is on the IUCN Red List as critically endangered.[3]
