My loach has now had this for two weeks. All over its body, you can see a woolly, fuzzy growth. It comes down to a fungal infection. He is still eating well, and my other fish are not affected. I have added EasyLife Fungal for five days, but it hasn’t worked. I cannot quarantine him because I can never catch him. He has been swimming here since May, and he has lived for years with the previous owner. What should I do?
