What's the deal with these venomous beauties? I heard thier venom isn't lethal to humans, only mild. Exactly how bad is their venom exactly, is it similar to a hognose or worse? I really want to get into venomnous snakes, but it's illeagel to own anything lethal like a copperhead where I live, so I was hoping to start out with a mangrove. I heard they are aggressive, but that's not a problem. How much do they go for? Thanks in advance.
