Can I add metro powder (Flagyl tablets 200 mg that I will crush to a powder) and prazipro to the water? I am feeding the powder in food but one of the fish won't eat. The one that won't eat at all is a Blonde naso tang. He is dark and has a pinched stomach. He is also breathing fast. These fish are in a 40g qt and I have only had them for a week and 1/2. There is the naso, gold flake angel, pakistani butterfly and a filefish.
