I recently rescued a gourami in a 10G. No idea how this fish is still alive. The guy (or gal) has almost no color, does have one red spot on the outside of each gill, and is thin. I have him in clean water now. He's eating well. Seems to be getting a little better. I have treated for parasites and that helped even more I think. Now... how can I get this fish's colors to return? Any ideas? Thanks!
