Every single living thing can become noticeably subject to the ailment in specific conditions and fish make no exemption. Goldfish are hardy, but sometimes they become illness like all the inhabitants of the aquarium. Due to contamination of bacterial, protozoan, infectious diseases and so on, goldfish become unhealthy. Diseases occur in aquarium condition with wrong tank management. For proper treatment, diseases should be diagnosed accurately.
Categories of Goldfish Diseases
The goldfish illness can be partitioned into non-infectious and infectious diseases. Some infections are more susceptible to goldfish. Non-infectious diseases occur due to improper aquarium maintenance, exposure to external factors, improper feeding, as well as mechanical injuries while infectious diseases are caused by bacteria, fungi, viruses, unicellular algae, parasitic worms and arthropods.

How to Prevent or Minimize Goldfish Illness?
To prevent or minimize goldfish diseases the following step should be taken:
Fungal Diseases of Goldfish
The fungus is a generally opportunistic pathogen and some are facultative. Fungal diseases are sporadic problems. Saprolagiasis and Branchiomycosis are the most common and widely spread fungal diseases. Generally, the fungal attack occurs in early spring, late autumn, and winter. It affects weak fish that have weak immune system due to prolonged low water temperatures and poor tank environment. The fungus can infect any wound due to improper handling with hands, nets, containers or sharp decorations. Fish may get injured battling each other, or they may have open injuries from bacterial or parasite contamination. These injuries are at hazard for fungal colonization. The filthy tank environment also allows excessive amounts of the fungus to grow. Ammonia and other organic matter wear away the slime coats that protect the fish and cause chemical burns. These burns then also get infected by fungus.
General Symptoms of Fungal Diseases of Goldfish
Cotton Wool Disease or Saprolagniasis of Goldfish
Saprolagniasis is commonly known as mould or cotton wool disease. It is caused by fungal infection. It is one of the most common goldfish diseases. When a fish becomes injured during handling with hand, nets, containers or sharp decorations, it could be susceptible to cotton wool disease. This sickness is very simple to identify. It makes a cotton-like development over the fish’s mouth, fins, and body. The cotton lik development can be white, dim, or darker.
Causative Agent of Cotton Wool Disease of Goldfish: Saprolegnia sp.

Gill Rot Disease of Goldfish
It is also known as Branchiomycosis. This disease occurs in the blood vessels of the gill tissue. It barricades the blood circulation in the gills and hemorrhage occurs; gills become mottled with patches of brownish discoloration. It disrupts blood flow resulting in necrotic tissue and allows the gills to be invaded by a secondary disorder such as a Saproglenia fungus. A mycotic fungal disease in goldfish is basically connected with stress or damage. Disease with Branchiomyces is quick, and is essentially brought about by algal blooms, over stocking, high water temperatures, and large amounts of ammonia in the tank.
Causative Agent of Gill Rots Disease of Goldfish: Branchiomyces spp.

Treatment and Preventive Measure of Gill Rot Disease of Goldfish
– 0.1% potassium permagnate (1 g of crystalline KMnCL per 1 liter of water);
– 0.05% trypaflavine (0.5 g trypaflavin powder per 1 liter of water).
Bacterial Diseases of Goldfish
The most common bacterial diseases are ulcer, hemorrhage and septicemia. Many bacterial pathogens causing infection are associated with virus and fungus.

Tail and fin rot of goldfish
It is well known bacterial disease. It causes erosion and disintegration of fin and tails. Tail or fin rot is normally an optional contamination that may infect your fish.
Causal Agent of Tail and Fin Rot of Goldfish: Aeromonas spp, Pseudomonas spp, Haemophilus spp.

Columnaris Disease of Goldfish
It is a contagious and chronic disease and is one of the most likely culprits. It is also called cotton mouth disease. It affects the external structures of the fish body. It is a contamination that hits goldfish, and other pet fish. This disease has a few extremely evident signs and side effects, which can be utilized to quickly recognize it from other goldfish sicknesses. Columnaris can rapidly kill a goldfish, so treatment must be quick.
Causative Agent: Flexibacter columnaris

Dropsy Disease of Goldfish
Dropsy is the development of liquid inside the body or tissues of a fish. It can show various hidden difficulties, including bacterial diseases, parasitic contamination, or kidney dysfunction. In an aquarium with running water, this disease rarely occurs extremely.
Causal Agent of Dropsy Disease of Goldfish
Dropsy diseases can occur due to various agents like bacteria (Aeromonas sp, Pseudomonas sp), Virus (Rhabdo virus), and parasites (Myxosporideans)

Bacterial Gill Disease of Goldfish
It usually shows in the gills linked to environmental stress and it is well known bacterial disease. It occurs when filamentous bacteria is present on the gills. Generally this disease is caused due to poor water quality, low dissolved oxygen content and overstocking.
Causal Agent of Bacterial Gill Disease of Goldfish: Flavobacterium branchiophilum (gram negative non-motile bacilli)

Swim Bladder Disease of Goldfish
Swim bladder illness or flipover, is a typical sickness in aquarium fish such as goldfish.
