Well I currently had a black moor who had a somewhat bad case of velvet. I thought he was gonna die. So i researched on the internet and actually found lots of useful info on velvet and some pictures of a black moor with velvet, I compared my fish to the pictures of the black moor and sure enough thats what it was. So i went to petsmart and was looking at all the reccomended medicines and the lady in charge of the fish department came over and asked what i was looking for and i told her the situation and she was very knowledgable (Props to a chain store hiring someone with a brain). She reccomended General cure By API, for parasites. I bought it and put it in the tank as soon as i got home. ( Yes I followed the directions very carefully.). And the next day The black moor looked great he was active and it looked like it was clearing up. Second day he looks even better and the color in his scales is coming back to that beautiful black that it was. It is the second day and i am getting ready to add the second dose as per the instructions. I just wanted people to know that the general cure works and saved my fish.
