Common fish illnesses include parasitic infections, bacterial infections, fungal diseases, and viral outbreaks.
Symptoms may manifest as abnormal behavior, changes in appetite, lethargy, visible lesions, or discoloration. One prevalent issue is parasitic infections, where organisms like flukes attach themselves to the fish, causing irritation and compromising the fish’s immune system.
Moreover, bacterial infections, often resulting from poor water quality, can lead to diseases such as fin rot or ulcers.
