So a we noticed that our Chalk Brass has one eye quite swollen, the upper part of the eye lid is a bright silver. The eye is not cloudy and again only one eye is affected. Does anyone know why this might be and how to treat it?
An eye infection. Is this fish a new addition or have you done maintenance on the tank recently? Added any new rock, or items to the tank? Netted the fish for any reason?
What are your water readings in the tank?
