new guy with question/observation

My Kribs had babies 2 weeks ago in my planted 10 gallon, and my babies all disappeared yesterday, this morning the male looked in very bad shape so I changed water and cleaned the sponge, and fed them ( I hardly ever feed them, maybe once every 3 days, it is a planted tank though). Anyway I figured out why the male was looking so bad, the female was relentless in chasing him, no matter where he was she would chase him all over. He found a place to hide though, but he can't come out or the female will beat him up. I was wondering if this may be some sort of retaliation for the male eating the babies, that is if he ate the babies, I'm not sure if he did. Is this a common thing for dwarf cichlids, the chasing I mean? Also all the babies were gone before the female started to chase the male around, I don't think it was the female trying to protect the babies, I guess I would call it revenge if anything. Under what conditions do females chase the males around with bad intentions? The female is not even bothering the pleco at all, in fact the pleco is eating algae off of the top of her rock. When they did have babies the kribs went nuts on the pleco, fortunatly he had enough hiding spots.

I serious doubt my lack of feedings is a problem because I've fed them hardly anything for months before they spawned, honestly I was shocked the female was getting enough food to even make eggs. Probably once a week I give them frozen blood worms, and once a week I feed them flakes or tubifex worms, not on the same day of course. There's 4 mollys, 1 ancistrus pleco (3" max), and the 2 Kribs in this 10 gallon, with 80gph powerhead/sponge filtration. And a little co2 injection, ph is around 6.5, temp hangs around 78-90 depending on the temp outside and wether or not I'm home to turn the AC on, it was only 90 once, usually 84 is the max. I'd call it average plant density. tap water too, hard stuff, however I just got my new ro filter last friday.
