Contents of the fish in the pond
The content of the fish, as well as other animals, is associated with a large number of problems. Problems so that their transfer could plunge you into depression, so it makes sense just to mention two important points.

Pay attention to unusual behavior of fish. You should be alerted if any of the inactive fish, while others are active.
On the other hand, if the fish show concern – for example, sharply rise to the surface, worn by the pond or rub against its walls – it is also a bad sign. The reason for the unusual behavior of fish can be internal or external parasites, disease, damage by pests living in the pond, and the wounds inflicted by a cat or a bird.
If you have any doubts about the health of fish, it may be wise to transplant it into a separate container with water and inspect more carefully the section “Inspection of fish.” You may need to carry out treatment – now there are many different products, but you need to make sure that the drug is intended to treat the disease and is suitable for a given species of fish. Carefully follow the instructions.

The tubular gray-white worm-like crustacean body length of about 1.5 cm, at the end of which is usually two egg sacs hanging outside. There are proprietary means of combating these pests, but often resorted to this method: Brush for drawing dipped in melted paraffin and touches it to the body of the crustacean. Then, using tweezers to pull out the crustacean from the fish’s body, the wound was treated with fish intended for disinfecting substance.
Cats often sit on the shore of the pond and watch the fish. Not surprisingly, they are often blamed for the loss of goldfish and redfins, although usually not to blame the cat. They do not like water and are not dangerous for healthy fish. If they sometimes catch fish, only sick or lazy.
Birds are much more dangerous to fish. Seagulls can snatch from the pond one or two fish, pretty kingfishers sometimes dive for small fish. But the main robber – herons, who hunt, standing in shallow water and waiting for its prey at dawn.
