Datnioides undecimradiatus

Common Names: thinbar datnoid, Siamese tigerfish, gold datnoid, tiger datnoid

Family: Datnioididae

Order: Perciformes (perch-likes)

Class: Actinopterygii (ray-finned fishes)

Max. size: 16 inches, although relatively slow-growing and long-lived

Environment: freshwater, rivers.

Distribution: southeast Asia, specifically Mekong River basin

Description (courtesy of fishbase.org): Dorsal spines (total): 12-12; Dorsal soft rays (total): 16-19; Anal spines: 3-3; Anal soft rays : 10-11. Body depth 2.1-2.4 times in SL; relatively narrow vertical bars, the first bar usually not continued onto thorax or across ventral surface of body and the second bar originating at the base of 5th to 6th dorsal-fin spine; usually 11 branched anal-fin rays (Ref. 27732); about 17 scale rows between upper part of lateral line and dorsal base (Ref. 10425).

Temperament: semi-aggressive, more aggressive towards same or similar species.

Water paramenters: Prefers clean water, pH 6.5-7.5, temperature 76-82 degrees F. Although primarily a freshwater species that requires no salt, also does well in light brackish conditions (up to SG 1.005). (As will be discussed later, other datnoid species occur in brackish conditions, hence the common misconception that all datnoids are brackish.)

Feeding: Although often fed live fish, this species can be trained to accept shrimp, krill, frozen brine shrimp, beefheart, earthworms, and even Hikari Sinking Carnivore Pellets.
