Hi everyone. I woke up this morning and saw my betta, Ace, although acting normal, looked different. His right eye was swolen and cloudy. I believe it is popeye so I did a 100% water change and also went to my lfs to medication. The only one I could find there was Bettafix, so im currently using that to try treating him. Is there anything else I can do? Also, do I have to take the filter medium out while treating?
