Therefore they always take with them in the boat Python. A few hours before the inclement weather Python crawls out of the boat and swims to shore. The fishermen only to hastily follow him.
Observations of fishermen and whalers show that the ability to react to upcoming weather changes have many marine animals. Dolphins swim in the shelter behind the rocks, the whales go away from dangerous reefs and shores to the open sea. Small crustaceans before the storm come ashore — away from dangerous waves.

In the first place. conceived as a small pond? If its depth is less than 50 cm, it will quickly heat up, the fish will suffocate from lack of oxygen. Or water you have to aerate more (it generally somehow have to aerate – e.g., mini-fountain). The minimum depth 80 cm Depth for the winter: about 2 meters depending on the region and the average thickness of the ice. Although in your case this is not true – telescopes and red beanie winter will not survive.
Secondly. need to peruse the issue with the water parameters. Apartment in the aquarium they are alone, in an open pond with a different water source might be completely different. If the difference is too big – fish stress, sores and even the threat of death.

Most often they are found in the soil column, but often planarians can be seen on the surface of the water, moving with the help of special cilia on the body. Because of this, they are also often referred to as the ciliary worms.
Planaria is a typical hermaphroditic, so after internal fertilization without the participation of other individuals on light appears fully viable offspring. The planaria eggs are resistant to high and low temperatures, so get rid of them is quite difficult. These worms there is no one specific organ of respiration, the aeration process occurs with just the skin. Continue reading
