The first sign of the disease is the appearance of a bluish-white border along the edges of the fins. Further, a bluish-white clouding begins to spread from the edges of the fins to the bases, red spots may appear - traces of blockage of blood vessels. The affected areas become inflamed and begin to disintegrate, the fins "disheveled", split, and then collapse, falling off in pieces. At the last stage of rot development, white sores filled with pus form at the base of the fin. The infection passes from the fins to the body and in the absence leads to death.
Symptoms of the disease
Fin rot is an infectious disease, but its pathogens are opportunistic microorganisms. These are bacteria of the genera Pseudomonas, Aeromonas and Flexibacter, present in almost every aquarium. But if the immunity of the fish is weakened by adverse factors, they become dangerous. Fry is more susceptible to disease than adult fish. And they develop rot faster, often leading to mass death of young animals. Neon, barbs, angelfish, labyrinth and viviparous fish are especially susceptible to fin rot.
In the early stages, fin rot can be treated well. Often enough to change the conditions of detention - raising the temperature to the maximum for a given species and regular water changes. If sick fish tolerate brackish water, then it is worth adding a solution of table or sea salt to the aquarium. You can also use short-term baths with salt or potassium permanganate. The causative agent of fin rot is sensitive to a number of drugs from a regular pharmacy. You can add chloramphenicol, biseptol, biomycin, streptocide to the aquarium. In the form of short baths, Bitsillin-5 and malachite green are used. Now there are drugs on sale specifically designed for fish. Among them, Sera baktopur, Tetra GeneralTonic, Antibak, preparations of the Aguarium Pharmacenticals series, watercolors, phyosept, and tripaflavin are effective against rot. As a rule, detailed instructions for use and dosage are attached to them. It is better to treat fish in a separate container, since antibiotics disrupt the aquarium's bio-balance and disable microbiological filters. Unfortunately, if the lesion passes to the body, treatment is ineffective. Such fish are usually discarded.
