Vibriosis disease is an illness caused by the gram-negative bacteria Vibrio anguillarum (Vibrio anguillarium). It is believed it enters the animal via their food and attacks the gastrointestinal tract.

Symptoms[edit | edit source]

Ulcers - Clinical signs of vibriosis are lethargy, loss of appetite with red spots on the ventral and lateral areas of the fish with swollen and dark skin lesions that ulcerate, releasing bloody pus. (Starting as reddening or blood streaks under the skin surface).

There may also be eye problems with cloudy eye, leading to pop-eye and eye loss. However the course of the infection is rapid, and most of the infected fish die without showing any further clinical signs than the ulcers. This bacteria often infects several fish in the aquarium and multiple lose is common unless treatment is rapid.

Treatment[edit | edit source]

  • Perform a 50% water change asap.

There are a range of products that are available.

  • The addition of salt to the water will not limit this species of bacteria as it can survive in salt water.
  • A treatment of potassium permanganate will reduce the level of organic material suspended in the water and will help to reduce levels of this bacteria.

Prevention[edit | edit source]

  • Do not over feed your animals. The bacteria eats uneaten food and the animal digests this.
  • Regular water changes.
  • Regular substrate maintenance.
  • Feed a range of good quality food so your animal has a healthy immune system to fight off infection.
  • Using a regular waste control bacteria media to reduce uneaten organic material on the substrate. See Competitive Exclusion.
  • Consider setting up a soil based substrate to limit the bacteria numbers. See Walstad tank.
