Easy husbandry? When you get into hots you should have enough experience to not have to worry about difficult husbandry issues... unless you're working with barometric pressure difference over a 24hr period

I've handled Eurasian Vipers (Vipera berus) and Western Cottonmouths (Agkistrodon piscivorus leucostoma and both are relatively small vipers. Have to be very careful... I'd rather handle something bigger (well, not a Bothrops asper) because I'd have more time to react.
