I know that feeling, in the past I have been sold several that were sexed wrong.
I did learn to pop and probe so I always check right away now, lol.
We were sold a 1.1 pair that ended up being a 2.0 pair and the breeders response was ooops, I guess I'm not very good at popping
The guy had no way to replace the snake and offered a different morph to make up for the boo boo, but it doesn't change the fact that now we don't have two identical snakes to breed to each other which was our whole intent.
*Don't smash your head, get someone to teach you how to pop, it's not that difficult really except with larger snakes* sorry, advise slipped in![]()
