Olive green-grey fish weighing less than 1 kg, with six or more dark vertical bands across its sides.
To help protect our environment:
Still or slow-moving waterbodies, lake margins, wetlands.
Contributes to poor water quality through consuming zooplankton, exacerbating algal blooms. Uproots plants, re-suspends sediments, can cause lakes to flip to alternative state devoid of vegetation with turbid water dominated by phytoplankton. Eats, competes with and displays aggression to native fish.
