Yeah arching like that is male combat/dominance, deff in breeding mode. Sorry to hear it, as well as the continued issues with Phyllis; you've been having the worst luck with the 'tics and you do so much to make it work. Gloves are a good idea, the bites can really do damage, slashing gashes that leave with nerve damage. Glad he only nicked you. If you have to rehome, it's totally understandable. I wish you the best!
