There are four categories of diseases: Bacterial Infections, Fungal Infections, and External and Internal Parasites.

Bacterial Infections

These are characterized by decrease in activity, color loss, bloated body, sores, abscesses, red streaks, skin inflammation, difficulty in breathing, and bulging eyes.

Fungal Infections

These can be developed as a result of an existing illness. When a fish is suffering from a fungal infection, it is darting here and there, scratching, and there is a presence of cotton-like tufts on skin, mouth, or eyes.

Parasitic Infections

Fishes that have been infested with parasites may exhibit inactivity, lack of appetite, too much film or mucus on the body, spots or worms, fast breathing, and scratching.
