Fish disease case nr. 273 Corydoras jullii with a bacterial infection and few skin flukes

Hello, free from parasites discus fish, it's really or not?

100% free of parasites (or bacteria) is never possible! But to have few parasites doesn't mean infection nor disease! Only when stress, lack of immunity, poor care, etc. makes the fish proneable to an outbreak...and an infection!
