RES have really stumped me since I stocked them late in 2011, they have been a tough nut to crack as far as figuring out how to catch them until recently.

In my opinion the are biologically geared to eating things near the bottom that are below them, things such snails, bloodworms, insects, and small YOY fish. In looking at many of the pictures I have posted their eyes are almost always focused downward. I do think that having eyes that are more sensitive to light allows them to make out things below them much better than other sunfish, but also makes it harder for them to see things above them. This also big reason they are difficult to feed train.
