Fish! They're just one hurdle after another lately... Yesterday my Blue Male Beta had an injury behind one of his fins - a few scales lost. I'm not sure as to how he lost them. It may have been on an ornament in the tank, that wasn't entirely smooth upon inspection. It has now been removed. Today it appears his injuries may be a little larger spread, and he's holding his fin down over it, so it must hurt a lot - my poor little guy. I'm going to change his water every second day, and include Stress Coat+ If his injury doesn't seem to be healing, or gets infected or worse... what should I do? Are there any Betta diseases that cause scale loss, without any other syptoms? Is it possible that this is a bacterial infection? I reference this for betta diseases, bacterial infection is the only one to mention open sores.
