Just got 4 C. marshalli slings (for a pretty good price, it was kind of a "sell-out")!!! The genus was among my favorites for some time now, but its species are quite rare here so I was very happy to discover these little guys. They have the biggest horns (afaik) in the Ceratogyurs genus, and they are awesome!!! Mine are only about ¾ inch now, but that just makes it even more better for me, I love to raise slings and watch them grow. Pics coming soon!
