Male suddenly stopped breeding?

Just wonder if anyone has seen this happen and if their is anything I can do or should be doing. I had one male who was breeding every week since the beginning of the season and then a few weeks ago he quit. He doesn't even seem interested. Any ideas?

Maybe the female is prego!

Maybe the females are knocked up.

Maybe he just needed to sew his royal oats.

Ive had this happen many times, usually when I'm pairing too often. Just give him a few weeks off and then start introducing him again and he should start showing interest again. Goodluck:gj:
