gaboons rhinos puff adders are not slow, they dont move because they are ambush predators if you mess up with one you will pay for it. gaboons and rhinos are pretty laid back but if you are in range and they want to bite you they will not miss and you wont get out of the way either.

i have kept venomous snakes for about 5 years and started with false water cobras then copperheads rattlers. my friend that i get my hots from started keeping venomous at age 14 and had puff adders he kept hots for 28 years before getting bit by a rattler. so i wouldnt get new venomous speices unless i talked to him first and he wouldnt sell me anything that i wasnt ready for or couldnt handle at the time, he sold me gaboons rhinos and puff adders before he would let me get a cobra.

Wow. If only there were more people like him...
