I purchased 2 silver molly's about a week ago and they almost immediately started getting black spots all over. They seem happy, healthy and energetic but I worry they have a disease or fungus. Can anyone help.
It's a disease called black spot. It's curable but it will take a few days or even weeks. I would add MelaFix, and if that doesn't work after a week, try PimaFix. I have run across it and have never lost a fish to it. You can also add salt.
