it is dissolve-able tablets that are used to treat fungal infections, fin rot, clamped fins, and dropsy
active ingredients are nitrofurazone, furazolidone, and potassium dichromate
I popped a little less than what was the recommended dose, ( 1 tablet per 10 gallons, so for my 55 quarantine tank I needed 5.5 but only added 4) cause I walk to the beat of my own drum...LOL, and went to bed, woke up and he was swimming below water level and even wanted to eat. I fed him VERY lightly, shrimp pellets, since they are good for digestion, and gave him just a few. I then waited two days and introduced him back to the original tank, now he is in tip top shape!!!
I also put bin laden the terrorist (RD) back in his own tank....
