I love all of the sunfish for their own reasons. How big are they?
As far as food, Newt pretty much summed it up. Younger fish are easier to train to pellets.
If you feed minnows, make sure they're healthy. Most store bought feeders are diseased and have malnutrition.
P.S. If you ever have an extra female green, think of me.
Well if they breed and i get some female greens out of the deal I'll let ya know....also if I happen to catch a wild one, would you like a small one if I catch it? I catch them all the time, alot of females out here in the lake!!
