Occurs in lakes and rivers (Ref. 56749). Prefers slow-moving water with thick vegetation. Feeds on a variety of plants and animals, including green algae and zooplankton (Ref. 6459) as well as aquatic insects near the water surface (Ref. 12693). Utilized fresh for steaming, pan-frying, broiling and baking (Ref. 9987); also processed as dried or salted fish; ripe ovaries are collected and separately eaten (Ref. 56749). Large quantities of small fish are exported for aquarium use in Japan, Europe, North America, Australia and other parts of the world (Ref. 9987). Very popular with aquarists due to its habit of sucking its lips and kissing other fishes, plants and other objects (Ref. 4833).

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this BS (Ref. 93245
Trophic Level (Ref. 69278
): 2.8 ±0.33 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Assuming tm<=1; Fec=40,000).
Vulnerability (Ref. 59153
