I see the bumps; I don't know what those are. You'll see a uniform swelling down the back half of her body indicating eggs. I've never seen it earlier than a couple of weeks after copulation, so I don't think that's what you're seeing. And with the females, I feed them normally for the first two to three weeks after mating, then giver her a couple of smaller meals. All of mine go off feed within a week or two of laying.

As for you guy; he's probably just refusing because its breeding season. Some of my guys continue to eat normally, some of them think they're bps and refuse to eat for a month or two. I wouldn't worry about it.
