Yeah, pretty sure it's a boy...This is the 'girl' I bought that turned out to be a boy....but he has no interest in the female he's in with...she's not being evasive or anything and is a seasoned breeder but he just has no interest.
Also, he's a phenomenal eater and hasn't slowed down at all during breeding season whilst the 2 other adult males couldn't care less about food. And before anyone asks...he shed last week so that's not an issue.
Thanks for your replies
