Hi, i just got myself an 10'' ornate but in the last couple of weeks its developed a white fungas over its eyes.sometimes one eye and sometimes both.It usually goes away after a water change but im just curious to why it keeps happening and what i can do to prevent it.I have it in a 2x1.5ft growout with an 10'' endli.I do 40% water changes twice a week.Also, i was told that the ornate was 3 years old which i thought it was a bit small for a fish of that age.Any thoughts?
