Two males locked

[Sloanreptiles]

I've heard stories of male locking with each other as a show of dominance. Never seen it but then again I don't put males together during breeding..

Thats exactly what we have heard. About 3 years ago we had a ball python we bought as a female and never resexed it, when we put the male in they locked up, about a year later I was sorta wondering why "she" hadn't produced. We popped "her" and it turned out to be a Boy! So that whole year two Boys were locking up!
