i use cooked market shrimp, the color on my two silvers has really "poped" since they've been feeding on it, one way to avoid eye drop is to avoid fatty foods and over feeding, and give them a varied diet..pellets..krill..shrimp..the occasional minnow..
heres one of mine about a month of eating shrimp(this was about 2 months ago)
