Enemies And Diseases Of Goldfish

When kept in an aquarium, goldfish have practically no enemies, except for the owner himself. Only through his oversight can various kinds of destroyers get into the aquarium. The first one who can do a lot of damage is the Cyclops. It should not be given in large quantities, otherwise not eaten, it attacks the fry. Another dangerous enemy is the dragonfly larva. She can exterminate up to 2000 fry in a week. A hydra caught in the spawning grounds can also inflict significant damage.

For adults, leeches, diving beetles and a domestic cat, which very deftly throws them out of an open aquarium with a paw, are dangerous.

There are not so many diseases, which are much talked about and written about, in goldfish. But if trouble happens, then the fish should be transferred to a spacious isolator (from 50 liters) and treated. Let my advice not seem seditious to the reader, but if the method described below does not help, then you should not torment the fish, since all other methods of treatment, if not immediately, then will soon send it to the next world. Of course, there are new medicines, thanks to which it is possible to save a sick fish, but as a manufacturer it will be forever lost.

A sick fish is treated in salt water (3-5 g of table salt per 1 liter of water) at a low temperature (not higher than 18 ° C).

Treatment is carried out in a spacious aquarium for three days, changing the solution daily. The water must be clean, not taken from the aquarium, but from the mains. If the disease does not respond well to treatment, then additionally, 1-2 times a day, the sick fish is bathed in a pink solution (1 g per 100 l of water) of potassium permanganate for 10-15 minutes. In a similar way, injured fish are also treated, which quite often get injured during transportation, transfer and cleaning of the aquarium.

During the treatment, the water is abundantly aerated. Sick fish during this period are not fed, only very weakened and fry are fed with small live bloodworms once a day.

The water from the aquarium in which the disease has arisen is completely drained, the soil is washed with hot water, the walls of the aquarium are wiped with salt and repeatedly washed off with running water.

Lerneosis

Clouding of goldfish scales. The causative agent of cyclochete disease is a small ciliary ciliate.

Symptoms of the disease. The affected areas on the body of the fish appear rough, dull when the fish is illuminated with a beam of light directed from below. The disease is dangerous because it entails other, more complex diseases.

Scabies. The disease breaks out from bacteria that multiply abundantly from not eaten artificial food.

Symptoms of the disease. The fish loses its brightness, becoming covered with whitish mucus, constantly scratching against the stones. The best remedy for the disease is a complete water change.

Dermatomycosis. Fungal disease of freshwater fish. It is secondary and appears on a fish whose body is weakened as a result of some illness, injury or poor conditions of detention. The causative agent is mold fungi from the genus Saprolegnia.

Symptoms of the disease. On some parts of the body, fins and gills of the fish, white thin threads (hyphae) appear, growing perpendicularly from its body. If during this period no measures are taken to eliminate the cause of the disease, the fungus will quickly develop and begin to resemble a cotton-like bloom. The hyphae of the fungus entwine the cells of the skin and gills, growing into muscles and internal organs. The fish becomes inactive and lays on the bottom.
