We have had this betta (Cinnabar) for about a month now. 6 days ago we noticed his eye was cloudy and swollen. We immediately moved him to a hospital tank from the community tank (with mollies and Glow tetras). We have been treating with maracyn for 5 days now (recommended directions) and I has not improved or declined. Should we continue the treatment or see if medicating with salt would work better? the tank parameters are GH- 100, KH-120, pH-7.1, and NO2 and NO3- 0, water temperature- 78F. This is the first time we have experienced this and would appreciate any advice! Thanks!!
