The reddishness and the cloudy eyes can be pretty inconclusive and may not be related. As I said in your thread, I personally would just be wary and observe closely. If the fish feeds well and behaves normal, there isn't much to worry about right now then.
As you stated this is a rescue from Craigslist, so the prior history and care are unknown. It probably came with cloudy eyes. If it came with clear eyes and they turned cloudy in your tank, then I'd be a bit concerned. Perhaps the prior keeper kept it in low pH water, while yours is on the high side, but really cloudy eye is very non-descript kind of a symptom it seems and the root causes can be numbered in dozen or dozens.
The reddishness could be from what it was fed before or also from a big change in water chemistry, albeit this is a pretty weak speculating, I'd say.
