I've heard some do feed supers as a staple. I feed mine a variety of mustard greens, roaches and supers. Except recently my boy Angel has decided he only wants supers. He goes through phases and will only eat supers. If I don't give supers for a few days, he eats like the girls, everything in sight. When I feed supers, I only give my dragons 1-2 at a feeding. Moderation is key when feeding supers without complications.
