| Description: | Osteoylossum bicirrhosum is a very agile and efficient swimming kind of fish which mostly stays in the surface water. It masterly understands to turn completely at one point. Caused by its lateral flattened and long stretched body it is able to follow its captured fishes into the dense tangle of under water plants. The wide cross placed mouth-cleft - typical for this kind of fish - takes up - without any difficulties - the capture, mainly all kinds of small fishes, out of the free water or from the water surface also to which the pursued fishes often press. But the uptake of an afraid small fish or a sunk down feed crumb from the bottom is also not difficult for this kind of fish. The fish shows the uptake of capture from the bottom with all details: Turning of the head to the feed crumb, tipping of the head and upper body towards the food crumb, stroke of the tail and counter stroke during the feed uptake, spreading of the gillcover and swallow movements of the fish. |
