I've had these two now for about two months, beautiful patterns. I did sell a few others out of the tank to make room, but I see being able to work with these natives as well worth it. Plenty of circulation in the tank-just have to make sure that the rocks stay on top of the aquarium to keep from having either of them end-up on the floor. Feeding on large Suckers, and the occasional large goldfish for fun (Don't mind the glass, inside has yet to be wiped down)
