I have a native tank with Darters, a small Bluegill, and some different minnows. They will eat the Bio-Blend Tropical color food, but will it help their coloration at all? Let me know what you think.
it should brighten them up in time but the blue gill will have to mature .. if you had a pumpkinseed you mite have to tint the glass on your tank because it'll be so bright
here's a pic of my lill blue gill ..
