I just got 3 silver dollars from a friend that was moving... I know nothing about Silver Dollars, other than their living params needed. so I was a little perplexed when I noticed a change in their eyes from my tank to his...
He had these fish in a 55 gallon tank, with NO heater. His water temp was 62F- my water temp is 76F. So, I got them home, dropped them, floated them, and released them.
I was convinced they were going to die, as all the silvers laid on their sides on the bottom of the tank. I turned the light off, and let them go. Came back an hour later, and they were all swimming around and fine, but there is a white film over their eyes that was not there originally..
I thought it was maybe from the temp difference, like when your glasses fog up, but it's actually on the eye..
here's a pic..
