Feeding live foods and really high quality pellets usually encourages bettas to breed (this is called conditioning). Females won't usually produce eggs without a male, and it can actually be harmful to have her full of eggs and not have them released quickly.
Males make bubblenests even without a girl, it's a sign of health. Don't worry, just 'coz Ares isn't building one, this doesn't mean he is unhappy. My male Angelo is in top health but doesn't build nests. Jerry and Rio only build them sometimes. Sometimes it can be brought on by a nice change in the tank - new plant that they like etc. Other times, a change in barometric (I think that's it...) pressure brings it on. Mine tend to build nests before rain.
I feed her Topfin Betta Pellets and mosquito larvae.. the latter which she wasn't too interested, probably because the recent batch were dead.

They know they're there, Ares has noticed Jupiter from between scooched-together tanks and while he flares, she shows no reaction.
My last betta, Calcifer - who suffered from being from petsmart

build a bubble nest shortly before he died, so I presume it takes a few days for males to adjust? The tank was thoroughly cleaned before Ares got moved into it, though. It only contains one plant, but the standards are almost the same as Calcifer's tank WAS, except more aquarium salt and finrot treatment because Ares had a small case because of all the moving.

Once a female is in good condition for eggs, how long does it usualyl take for her to make them? Do they just pop up out of no where?
If she does get eggs, I'm hoping to breed the two together sometime in October (heh, if super deltas an vts look decent together.

I know if I get vts my lfs will buy them, at least, so that's good.), once I pay for all the tanks and background medicines.. which I still need to raise fifty dollars for.

Is there ever a case where a female NEVER produces eggs?
