Hello, I have a captive bred juvenile Imperator that I've had for about 3 weeks. He's probably a little over 1.5 inches. He's in a 20 gallon isolation tank with no other fish. He's been doing well eating mostly pellets. The other day I noticed the tank water was a little cloudy and I did about a 50% water change. The cloudiness has since cleared up. Today I noticed that his tail is frayed at the edges and his breathing is labored. I've added another airstone to the tank. What should I be treating him with. I'd really hate to lose this fish.
Regards,
Mike W.
