full grown silver dollars are 3+ years old, in a 45 gal freshwater tank (1+ year setup), temp ~80, dual Emporer 280 bio wheel filters, 1-2 inch gravel, 1 live plant, food is Hikari Chichlid gold and occassional blood worms/tetraalgae flakes.
I know they are living on the edge and could stand a larger space to live in, but I change my water every 1-2 weeks simply with a python gravel sucker exchanging the water until the level almost causes the filters to stop sucking (two times).
This keeps the water clear, but occassionally 2-3 of my fish will get puffy, fuzzy eyes
with a spot
on their side like they rubbed off the skin or something?
It may not be a disease that I'm asking about, but a injury from smashing into underwater heater or leaping into the plastic hood or filter intake since I do scare them once in a while when I get up at night and freak them out.
Also, I might see a stringy thing of growth coming off the eyeball when they get that cloudy/puffy symptom.
I usually just change the water extra and these symptoms go away in a week or so. I want to know what the illness is and what I can do to stop them from suffering.
I have 2 pictures of the spot disease: http://www.tropicalfishkeeping.com/m.../disease-1300/
