As with all types of catfish brohisy are nocturnal. They are very mobile and swim in small groups, so it is desirable to keep their flock of several fish, with a greater proportion of males. Fish swim in a substantially lower water layer, occasionally rising to the surface in order to swallow a bit of air. Brohisov can be kept in community tank with the same peace-loving fish, as they are.
To keep the aquarium for a spacious capacity of 100 liters, densely planted with plants, including floating. There must be a large number of shelters in the form of snags, rocks and caves. As the soil is desirable to use sand or gravel wiped. In the aquarium should not be any sharp objects, as Fish digging can damage his mouth. Continue reading
Breeding carp in the garden pond
Every caught carp was caught in its own way the time sweeps were individual for each individual.
Implement feeding carp must not more than 2 times per day, limited doses because an overabundance of food will create the conditions for the decomposition of organic matter, leading to algal pond. If the cold period of the inhabitants remain in the water, they need to stock up on nutrients, to spend the winter, as well as the coming of spring they need to recuperate. An artificial pond needs to be built by all the rules. Acne is a predatory fish with a long body, eats other fish eggs, small fish, frogs.

The ancestors of modern sharks appeared in the oceans some 350 million years ago. The Earth looked very different then than it is now: continents and oceans have not yet purchased our usual shapes. Ancient sharks swam where nowadays sow wheat and build cities. Therefore, fossils of sharks sometimes discover for tysychi kilometers from the sea. Paleontological scientists studying ancient forms – most often find shark teeth. Fossil shark teeth affect its size. Most krupnye- length of 15 cm. And a weight of 340 g – belonged to the monster in the mouth which could put a man gets up to his full height, and it reached 13 meters in length!
After hundreds of millions of years, descendants of the ancient sharks overcome thorny path of evolution continue to surf the seas and oceans. Sharks, of course, in many ways inferior to more progressive in structure bone fish. Sharks do not have kostey- their skeleton is composed entirely of cartilage (though their ancestors had the skeleton). The gill slits are not covered shark gill covers. And most importantly, sharks, like all cartilaginous fish, no swim bladder. In part, though, the swim bladder shark replace fat deposition in the liver. To stay in the water and sink to the bottom, the shark spends his life in constant motion. Sleep she also prihoditsya- not only coastal and reef sharks can afford to rest on the bottom underwater caves. Gills sharks are not so
