Either or both of you Cecil. I'm sure you certainly know that fish have, for the most part, a pasty, washed out, colorless look in turbid water and more coloration in clearer water. I've also noticed that fish, of the sunfish family, on high protein feed have a lot more coloration.
If you have 3 ft of visibility, I figure it's either the feed or Dr. FrankenBruces strange machinations and manipulations of the gene pool.
It would be interesting to segregate some to change feeds and/or visibility into test and control groups to determine the causes.
