One of the most common diseases that affect tropical fish is fin rot. If you keep freshwater aquariums, you’ve probably already encountered this disease. Luckily, it’s easy to identify, and there are ways to prevent it and even cure it.
Common Fin Rot Symptoms
Most freshwater fish have smooth fins. A fish with fin rot develops jagged, receding fins. The tail fin is usually the first to show signs of fin rot. However, fin rot can also affect the other fins like the dorsal, pectoral, and pelvic fins.
The easiest way to tell if a fish has fin rot is by looking at the edge of its tail and fins. If the fins are uneven or jagged with fuzzy white specks, your fish more than likely has fin rot. Fins can also turn opaque and inflamed when inflected with fin rot.
