Rotan firewood (Chinese sleeper) in 1948 was brought by biologists of Moscow University from the Far East. And next year, this fish was already bred by many Moscow aquarists.

In an aquarium, rotan reaches 10-12 centimeters. The large head with the lower lip protruding forward was the basis for the popular name of the fish. The round, thick, elongated body ends with a rounded caudal fin. Rotan has two dorsal fins, and the back one in males is much larger than the front one.

Large dark brown spots are scattered over the brownish-gray background of the body, forming a carpet pattern. During the spawning period in males, these spots turn black, and the spaces between them form a complex bluish pattern.

Rotan is distinguished by its exceptional unpretentiousness and undemandingness. He lives well in cold-water aquariums, content with small (from a bucket for a couple of fish) rooms.

It is necessary to keep rotans separately, as these are predators that attack other fish, sometimes not even inferior to them in size.

When rotans are fed with small fish, you can observe their interesting hunt. Having noticed the fish, rotan slowly, with movements almost imperceptible to the eyes, sneaks up on its prey. Having swum to it at a distance of 8-10 centimeters, he rushes forward with unexpected speed and hits almost without a miss. Rotan is very voracious. In three days, he can eat about ten adult female guppies.

Rotans reproduce well in aquariums. When the spring sun begins to warm the water and the well-growing plants emit a lot of oxygen, the males dress in spawning outfit, become pugnacious and begin to chase the females.

For spawning, it is best to put half a flower pot in the aquarium, making a small cave out of it. Rotans will stick eggs to the inside of the pot, after which the female must be planted.

The male selflessly guards the nest, angrily attacking any swimming fish. Try sticking a thin stick into the aquarium. As soon as you bring it closer to the nest, the rotan will pounce on it with ferocity and grab it with its mouth so tightly that it can be pulled out of the water.

The male is removed from the fry after they have spread through the aquarium.

Amur sleeper bred in aquariums were released into several Moscow ponds. There they took root well and multiplied strongly. The one-year-old rotans caught from the pond are larger than their relatives grown in the aquarium, they are much paler in color and are more sensitive to the oxygen content in the water.
