Poor water quality stresses the fish, weakening their immune system and making them more susceptible to infections.

Symptoms of tail rot include fraying or disintegration of the fins, discoloration, inflammation, and bloody patches. If left untreated, tail rot can lead to severe health issues. Prevention is key, involving maintaining a clean aquarium environment and swiftly treating tail rot if it develops.
