This species of datnoid survives best in brackish water, with a specific gravity between 1.002 and 1.007. It prefers a pH of 7.6–8.0, and a temperature of 22–26°C (72–79°F). The Siamese tiger fish 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. Wild Siamese tiger fish grow to 24 in (61 cm). Captive ones are generally smaller, though may still require a large aquarium since some Siamese tigerfish have been grown to 16 in or more in length.
