Adding antibiotics to the food of goldfish is the ideal quantity, but you might have to increase it a little bit in severe cases. It is not advisable to use a more potent dose if the situation is not critical to avoid unwanted side effects. Goldfish might not want to eat medicated food ordinarily; therefore, the best thing to do is to starve them a little bit before feeding them.

What Is Red Pest Disease?

Red pest disease is a disease that significantly affects the general welfare of fish. The condition causes red spots on fins and tails of fish, thus allowing it to appear like the fish is bleeding. These bloody streaks can appear on fish fins, tail, and body of the fish.

The bloody streak does not have to appear in all the parts before you know it is red pest disease. It sometimes affects only either the body or fins. The causative bacteria agent of this disease is an opportunistic bacterium and often gets a hold on weakened fish.

These streaks could proceed to become ulceration, and it can consequently lead to fin and tail rot. In severe cases, the decay can cause tails and fins to fall off entirely.

Red pest disease mostly affects weakened fish or fishes that are living under a poor water condition. It is sporadic for red spot disease to affect healthy fish living under healthy conditions in a clean tank. It is not a contagious disease, and other fishes cannot be infected.

Causes Of Goldfish Red Pest Disease 

Red spot disease in goldfish is mostly as a result of bacterial infection and poor water quality. In most cases, these two factors can complement each other to make goldfish susceptible. Ordinarily, these causative bacteria cannot get hold of healthy fishes, and poor water quality can affect the health of the fish.

Red pest disease can be a result of infection from a bacterium known as Bacterium cyprinid, which is an opportunistic organism that cannot affect healthy fishes.  Bacterium cyprinid is a pathogenic bacterium common in aquariums, ponds, and other aquatic environments.

Likewise, red spot disease can also be caused by a fungus known as Aphanomyces invadans. It is typical for showing red lesions or bleeding streaks; it can result in deep ulcers. Aside from the fact that this fungus can cause red spot disease on its own, it can also make room for secondary bacterial infection.

Also, non-living factors can be responsible for the red spot disease in fish. Poor water conditions, poor feeding, high level of ammonia, high nitrate level, and other water parameters can significantly affect red spot disease in goldfish.

Ammonia poisoning is one of the most significant factors that can make goldfish susceptible to red spot disease. Ammonia poisoning happens when the nitrogen cycle of the tank is offset by the increase in the tank’s pH. The deterioration caused by ammonia is evident because of the red streaks or bloody patches on their body and fins.

Severe ammonia poisoning can also lead to damage to the brain, central nervous system, and other internal organs of the fish.

Is Red Pest Disease Contagious In Goldfish

Red pest disease itself will not spread from one goldfish to another, The disease is spread through poor water conditions, so if one of your fish has the disease, your other goldfish will most likely also get the disease.

Red pest disease will attack and infect goldfish that have weak immune systems.  If your fish are in poor water conditions it is only a matter of time before they will get poorly.

The red pest disease will come from some bad bacteria in your tank, check for the source such as

  • Dead Fish
  • Rotten Food
  • Blocked / Dirty Filter
  • High or Low Levels of pH and Ammonia

Recommended Antibiotics For Treatment

There are a variety of antibiotics that can be active as internal medication for red spot disease. Tetracycline and chloromycetin [chloramphenicol] are the two most common antibiotics that are effective in the treatment of red spot disease. The concentration of these antibiotics is also crucial in determining how effective it will work.

If for some reason, the fish fails to ingest the food, you can add the antibiotics directly into the tank. You can add 10mg of antibiotics per 1 liter of water. This method is, however, not as effective as mixing antibiotics with fish food.

You can also clean the tank with fish disinfectants like acriflavine [trypaflavine] and monacolin [mono aminoacridine] to water if you perceive the presence of the red pest in the tank. You should, however, discontinue the use of antibiotics if the fish are not comfortable with it.
