Hi!
I have a 13” common pleco with one cloudy eye. For a while I did daily ~25% water changes, but it didn’t seem to help. I’m not sure what to do for him now.
He lives in a 36 gallon tank by himself. He used to live with a pair of angelfish when he was smaller. I’m looking to upgrade the tank; ideas on size welcome. He’s 5-6 years old.
Any help appreciated!
