I have a peacock (~4.5") that I pulled out of my DT a month or so ago due to lack of appetite. I put him in his own 10g. He has not improved nor degraded over that time. This morning half of an eye is cloudy. I have some API General Cure but should I treat for fungal? I maintain the params of pH: 7.9-8.1, Nitrates: <10 and follow directions for freshwater salt concentrations.
