convict laid eggs and now i cant find them

I have a 30g tank with a pair of convicts the female laid eggs in the flower pot I had in tank. everything seem fine the male and female guarding the eggs. after a couple days the eggs are gone im not sure if she ate them or moved them? im new to all of this...... at first all the darker eggs were with some eggs that were white "which I think where not fertile" and then I looked today and all the darker eggs gone but the white ones still in the pot. Now all the white ones are gone. the female still goes into the flower pot but now the male keeps chasing the female like he is angry. what are your take on this? did she eat all the eggs and piss the male off? or maybe they are hiding

I don't think so I don't see anything now. would have been wrigglers by now
