@Bochelly Don't be too upset, nothing wrong with having a male. He's a Brachypelma, so you'll still have him around for quite some time, and when he matures it'd be super easy to find someone to send him to on a breeding loan. If the pairing is successful, you can end up with a bunch of his offspring to keep as well. Don't let him being a male ruin the joy of keeping him.
@Bochelly It sucks but I wouldn't get too upset over it, there should be a decent demand for males from breeders as this is one of the rarer Brachy species in the hobby so you can either recoup some of what you paid for him by selling to a breeder or send him out on a breeding loan and get a % of a sac if successful
