I've had a few dozen over the years all wild caught my cousin who lived in Waco would catch for me. yes some of them tamed down some didn't. but snakes bite out of defense and if you put them down just cause they bite you they will see the pattern that if they bite they get put down. no snake is OK with being held some deal with it with-out biting though but just cause they don't bite mean they like to be held. best you can do is show them you aint going to hurt them.
right now got a few ball pythons a few green tree pythons (tame enough to hold took getting bitten a few times and not letting them think i was scared of them biting me) Burmese blood python. gargoyle geckos Tokay geckos. Goliath bird eater about year old so not full grown yet.
lets see herps i have kept in past Burmese close to 20 foot when gave to zoo cause couldn't afford the food anymore. copperheads, cottonmouths, coral snakes, western and eastern diamond backs, and timber rattlers. rainbow boas, king snakes (cali, prairie, grey banded) milk snakes (MOUNTAIN KINGS, NELSONI, HONDURAN) countless anoles all types. iguanas a dozen or so (cousins son use to buy them when on vacation then when they tail whipped him they found there ways into my collection) black racers, blue racers, garters corn snakes. yellow anacondas had a breeding trio (also given to zoo once they started pushing 12 foot one had good temperament other 2 were mean as could be) think thats it will have to check old records to see if there was more went off what i could rember off the top of my head
black rat snake, yellow rat snake, Everglades rat snake, Grey rat snake
