US. Thanks for your help! He's actually looking better today. He now prefers the top of the tank and is swimming around some. His reddish discoloration is alot less than yesterday. I started feeding him that anti-bacteria food but he's not really thrilled about it. At the store the merchant recommended a garlic-juice supplement that you soak the pellets in to make them more tasty. I will probably get that today. Again, thanks for your help. It is always greatly appreciated.
