I have had all but bp's eat for me in the last 2 months. They are both female that have stopped eating so I'm not to sure what exactly that's about. All my males are back on feeding. Anyway, I don't let it bother me unless they visually start losing weight.
I wouldn't offer him food every week as this might cause him to stress as well. Try every 10 - 14 days instead. Good luck and I can't wait to see pics of him. I love balls!! LOL
