If you are thinking of keeping Cardinal tetra, there are a few things that you need to know and keep in mind. First, this fish’s disease is a significant problem that arises after keeping the fish in an aquarium. Among the many conditions, dropsy is the most prevalent in Cardinal tetra.
Dropsy in Cardinal tetra is a condition that can occur due to an injury, illness, or infection. It occurs when the body tissues compress, and fluid accumulates in these areas. Dropsy affects all body parts – head, eyes, mouth, etc. It can also indicate other problems such as liver damage or kidney failure.
Dropsy can lead to death if not treated quickly. So every pet owner needs to learn how to diagnose and treat this condition. Thus, this article will be all about dropsy in Cardinal tetra.
Dropsy In Cardinal Tetra
Dropsy is a disease more common in fish than in any other pet. It can occur due to a bacterial infection, parasitic infestation, or even severe kidney failure.
Aquarists refer to the disease as dropsy because of its effect on specific internal organs. It causes them to become swollen with fluid (edema). This swelling becomes visible as tumors in the fish’s body.
As a result of swelling, air bubbles trap under the scales of a tetra and cause imbalance. Besides this, malnutrition, poor water conditions, and viral infection can also cause the fish to drop.
If you spot an afflicted Cardinal tetra, there are some effective treatments that you can apply for this disease, such as a combination treatment involving Kanamycin and Acriflavine-Zinc. This combination usually cures the problem. However, it is crucial to follow the dosage and treatment time correctly.
What Are The Causes Of Dropsy In Cardinal Tetra?
There are various causes for dropsy in cardinal tetra, but the most common infection is Aeromonas or Pseudomonas bacteria. These bacterial infections occur due to poor water quality and low immunity levels in the fish.
Moreover, some of the causes of dropsy in cardinal tetra might be:
Physical damage can cause Ich to spread through your tank. In addition, physical damage allows the parasite ich to break into the cardinal tetra’s body.
Cuts or wounds can become infected with bacteria, most commonly ich parasites. The cardinal tetra’s immune system will fight off the parasite causing this infection. While at the same time fighting off any other illnesses that may be present in its body after an injury caused by an outside force.
Bacterial infections are common in aquarium fish. There are many ways to contract these infections, such as the water, food, and other fish that may have an illness themselves. Some bacteria may be harmless to the fish. But others may lead to a systemic bacterial infection that can cause cardinal tetra drop. Such as Aeromonas bacteria.
Cardinal Tetras are very susceptible to parasites because of their small size and intimate living environment with fishes. There have been reports of several types of parasite infestations on cardinal tetra. Moreover, the most common parasite in these fish is Ich.
Lack of proper diet encourages the Cardinal tetras to feed on plants and wastes present in the tank. So, there will be a higher probability of them contracting from dropsy.
Tap water is not safe for aquarium fish if you do not treat it before use. Most tap water has chlorine or chloramine, which damages aquatic animals’ gills and makes them sick.
Improper or Wrong Medication
Using inappropriate medication will not only harm the fish but also other inhabitants in your aquarium. So, always check if you are using the right kind of medications(approved by Vet) before applying them to your tank water.
Lack of Good Hygiene Practices
Maintaining good hygiene practices in your aquarium is vital to keep the fish healthy. You should always clean and change the filter regularly. So, perform regular tank cleaning for better water quality, ideal for aquatic life.
It may also be hereditary, where some fishes are born with a weak immune system that can’t fight off the disease.
Improper or No Quarantine Period
Quarantine is the process of keeping sick fish in a separate tank to prevent them from infecting other healthy fish. If you do not quarantine your new or sickly fishes, they will most likely suffer from Ich infection. And this will cause problems for all the other inhabitants in your aquarium.
