Yup, males when bred will continue to want to breed. I think it helps the more distance you can put between them and certainly don't be like my inlaws that leave just a pane of plexi between the poor things... he goes at that clear wall all summer long!

Give him a bit if he's not eating, just moving enclosures can put them off food for a bit, so unless it goes on for months I wouldn't be too concerned. (Assuming proper weight/husbandry/yadda yadda.)
