It's a hard choice. I like them all, too. I haven't personally kept any of these species, so my opinions are based solely on sporadic interactions with the animals at shows, or in friends' collections, or through anecdotal stories.
Corns are just great all around snakes. So many different morphs, and not too expensive to get into, relative to many of the other species morphs.
Judging only on stories I've read, Texas rat snakes are probably the most difficult of those species, as far as personalities go. They tend to be very flighty and nippy. But some people prefer that in their snakes, too...keeps 'em interesting. LOL
Hog noses are just the cutest little boogers in the snake world.
Sand boas are also cute and very cool little snakes. I've seen some pretty neat morphs for these guys, too.
I put my vote in Cali Kingsnakes. If I could choose to keep only one species off that particular list, that's probably what I'd end up going with. I love their adult size...I love their general overall temperament...and I love all the really cool pattern work you can do with them through selective breeding. You've got white and black, yellow and chocolate, plus the albinos. You've got banded or striped. Solid stripes or broken stripes. Spots, even. I never get tired of poking through every deli cup at a show that has a cali king in it.![]()
