I've kept them, they stop musking pretty quickly and tame easy, I fed mine baby sunfish and earthworms.

dekay's brown snakes do poorly in captivity, however water snakes are easily kept, care is similar to most turtles except diet, as a matter of fact water snakes can be kept with map and razorback musk turtles, I often store them with baby turtles, water snakes also tame easy which is surprising given how much they bite when u grab a wild one.
