Observations on General Behaviour of an Anabantid Fish, Colisa fasciata

The anabantid fishes (modern bony fishes) are vegetable and animal feeder. They have excellent capacity to adapt in various types of habitat like freshwater, slightly brackish water and even polluted water where the DO₂ is of least amount. They can also survive in aquarium conditions very smoothly and feel natural environment in it. In the present study, considerable efforts have been given to observe the general bahaviour of an anabantid fish Colisa fasciata. The general bahaviour pattern of C. fascaita consisted of various motor pattern, e.g., swimming, hovering floating, fin-flickering, flexing, chaffing, snapping of mouth, air gulping, bubble blowing, resting, fright and feeding behaviour.
