![]() ![]() ![]() ![]() Living in an environment with “abundant underwater interior or vegetation”: driftwood, thickets of plants, rocks, and other fish, have a stocky body, often flattened from the sides, usually with large fins. In simplified terms, these differences are as follows.įish-swimmers, keeping in the upper and middle layers of water with a strong current, has an elongated torpedo or arrow-shaped body, with a flat back and a weakly expressed dorsal fin deflected back.įish that live in the same conditions, but in calm, stagnant water, have a laterally elongated body shape and more developed fins. ![]() These factors are ideally embodied in the smooth, slimy body of the fish, without a neck, with a pointed head. However, depending on the behavior and the specific habitat (water layer, current velocity, and other habitat conditions), the shape of the fish body can also be different.īy distinguishing the “structures” of the fish body, the aquarist will be able to imagine in which layers of water the fish acquired by him prefer to live, as well as the circulation of the aquatic environment of what intensity they need. Over the entire time of evolution in the aquatic environment, fish have developed a body shape that is ideal for smooth sliding, quick jerks, the development of high speed, and vice versa “hovering” in the aquatic environment. And all this – with minimal energy consumption. ![]()
