My Pyjama Cardinal has popeye and has been in a quarantine tank for just about 2 months. I dosed Maracyn II for 3 weeks with required water changes and then did a full water change and switched to Erythromycin for 2 weeks. I did also add a bit of Epson salt 2x during the end of my Maracyn II treatment. Then I took a break for about 10 days. Although she looks better than when I initially started treatment we are at a standstill and it is not going down. I put her back in the display last night to see how she would do and the eye looks more swolen than yesterday in the quarantine tank. Her bahavior seems to be ok and she has been eating fine. Any advice is appreciated
