I have 2 KSB females and love them. I have a female nuclear who's color is just awesome and an anery with great contrast. They are beautiful, but aren't out very often. Both of mine have been easy keepers and good feeders.
I also have a male hognose (western) and would not recommend one of them... Mine (and I've heard numerous others) is a problem feeder... Even though he was eating f/t pinks just fine when I got him. He's been on and off food for a long time now and is undersized. He also "runs" a lot and does not like to be picked up.
