Thanks. I don't know how to start a new thread yet so I could only post on a similar one. The water is pH 7, ammonia levels are 0.25, nitrate and nitrite levels are 0. I do 50% water change every week. I tried to stop feeding for two days but that did not work. I brought the air bubble closer so that he can have more oxygen too it does not work.Could you newbies start your own thread? I'd like to help but I'm confused...Canail Siren, what water tests? What results? 2 months is not unexpected to have some issues but maybe 2 x water changes or more per week might be needed.... Tell us more...everything you can!
The cory became more transparent and stopped moving.
