Red spot in fish

Red spots in fish are a sign of hemorrhagic blood poisoning. This bacterial infection is also known as the Red Plague because of the distinctive red spot that can be seen on the fish. In this article, we’ll tell you everything you need to know about it.

Red spots in fish: a sign of hemorrhagic blood poisoning

General

Hemorrhagic blood poisoning is caused by the Aeromonas bacteria. This affects the tissue, blood vessels and heart of the fish. This results in internal bleeding, after which the fish can go into septic shock. In addition, the moisture that the fish retain can cause dropsy of the stomach. Hemorrhagic blood poisoning is in many cases fatal.

Symptoms

Depending on how far the disease has progressed, you can recognize hemorrhagic blood poisoning by the following symptoms:

  • Distinctive, bright red streaks on the fins
  • Spotty, red discolorations on the body
  • Bulging eyes
  • swollen belly
  • open sores
  • Rapid breathing or hyperventilation
  • Gasping for air at the surfaces
  • Changed swimming behavior

Causes

Hemorrhagic blood poisoning can be caused by different organisms or a spike in ammonia levels. In most cases, this is triggered by contaminated aquarium water, due to too many decaying organisms or overcrowding (too many fish in the aquarium). This is often accompanied by high nitrate values. If the fish already had a poor immune system, they are even more susceptible to the disease.

Therapy

There is as yet no medicine that can cure this disease. It is a disease where quick intervention is the only chance to save your fish. If not (yet) all fish show symptoms, the sick fish should be isolated in a separate aquarium. In addition, you should add antibiotics to the fish food. Trichosal 100 ml against fish diseases is a good option. Whether it catches on is a matter of waiting. Also make sure to remove any rotting organisms from the water. Test the water values ​​and try to reduce peaks in nitrate and ammonia.

Tip: Make sure not to overeat your fish during the treatment. If they are a little hungry, they will ingest more of the medicine before it can dissolve.

Prevention

Prevention is better than cure, especially when it comes to red spots on fish. To prevent hemorrhagic blood poisoning, it is first important to keep your aquarium clean. That means changing the water regularly and removing rotting leaves and other organisms from the tank as quickly as possible. In addition, you can give HS Aqua Fish Guard to strengthen the immune system of your fish.
