Racking my brain for the answer over the last few days and I just can't seem to settle on a choice of what to buy. I've decided on subspecies at least that I want either a mexican black king snake or a Californian king snake.
Now personally I think the Mexican Black does look absolutely awesome, probably my favourite looking king as of yet, but I do want to have a pair to breed to give me something to do while the royals are on their off season, in which case I think I would have far more fun breeding a pair of Californian king snake morphs as I'd get the thrill of wondering what is going to pop out of which egg and such...
I think MBK is winning, I was going to buy cali kings purely because my local shop has them in stock and I like to show loyalty but they're not sexed and I've never sexed a colubrid they're little tiny things I might snap lol so think instead I'll go MBK when I can find somebody who sells them!
