Black skirt tetras are popular freshwater fish that can be found in aquariums all around the world. Unfortunately, these beautiful creatures are also susceptible to fungus infections. This blog post will answer your questions about how to tell if your black skirt tetras have fungus and what steps you should take to treat them!
Fungus, also known as fungus disease or mycosis, is a general term for several types of parasitic fungal infections. The fungus can be found in the air, soil, and water. It causes serious diseases in plants and animals including humans too.
When it comes to aquarium fish tanks, the fungus is most commonly seen on black skirt tetras due to their sensitive skin that makes them more susceptible to infection than other species of freshwater fish.
What Is Fungus Disease In Black Skirt Tetras?
Fungus Disease in black skirt tetras is caused by fungi such as ichthyophagous hoferi, chilodonella species, and cryptocaryon species.
Causes Of Fungal Infection In Black Skirt Tetras
Fungal infection in black skirt tetras is usually caused by poor water quality.
Poor Water Quality
The poor water quality means that the water is not clean and has a high level of dissolved organic matter.
This can cause an increase in the number of bacteria and fungi present in the water.
The water temperature can also affect the number of fungi present in the water.
Fungi grow better at a lower temperature and so they are more prevalent in cold water.
Coldwater can also cause fungus infection in black skirt tetras.
Signs Your Black Skirt Tetras Has Fungus
You may notice small white spots on your black skirt tetra’s body. These are the signs that your black skirt tetra has fungus:
These spots are caused by fungi eating away at your fish’s skin and fins, causing them to rot away.
Black skirt tetra’s that have fungus will have red patches on their body or gills. They might also be scratching against rocks or gravel because the intense itchiness caused by the lesions from fungal infections can cause fish to scratch themselves against objects which could lead to secondary bacterial infections.
The infected area will be swollen and inflamed which will result in damage to internal organs if not treated immediately.
Lesions and Sores
