Rust Disease is a fungal infection that affects many species of freshwater fish. It’s caused by the fungus Saprolegnia, which is found in most freshwater environments. The disease can be identified by the reddish-brown spots on the affected fish’s skin and fins. In severe cases, it can cause death if left untreated.
Rust Disease is spread through contact with infected fish or water, as well as through the introduction of contaminated food or plants. It’s important to quarantine any new fish before introducing them into an existing tank. Quarantining them will help prevent the spread of the disease to the fish you already have.
Symptoms of Rust Disease in Freshwater Fish
