If it may be fertile and was laid today I would try and incubate it. My pygmy tanks are also misted 2-3 times a day but sometimes the females find a dry part of the tank to dig and lay their eggs.
About 10 days ago I had 3 laid this way, when I got home from work all 3 had started to dent. All 3 of the eggs bounced back within hours of being put into the incubation medium. I checked earlier today and 2 of the 3 eggs are looking great.
