Hi there, wondering if anyone can help. I inherited some fish and have had them for a few months… yesterday I noticed the Albino Cory Catfish has some red patches towards the end of her body (Google tells me it could be red spot disease). This morning she was lying on the bottom upside down but when I moved the plant she was lying beneath she swam away and rested right way up. I just checked on her again and she doesn’t not look good but is still breathing. I just don’t know what to do. I find looking after fish stressful and I feel so sad when they die. Is she at the end of her life? Any ideas?
