Female discus is not quite interested in food should I worry?

Hi all,

I acquired a discus pair about 4 weeks ago, male is 6" and female is 5.3". My female is NOT quite interested in food:embarassed: while my male will accept anything I throw in tank. Should I worry about the female? They have layed eggs twice already in past 3 weeks (they eat both batches). I know that breeding is an energy-consuming process, I really want my female to eat well before any breeding activity occurs.
Following are my parameters:
My pair is in 29G tank, two sponge filters, water is at 84F-86F.
Ammonia 0, nitrite 0, nitrate 10-20 ppm
water change: 50% daily mostly (sometimes I am too busy so I didnt change)
I feed mostly dry food: different flakes, pellets, FDBW cubes; and sometimes Hikari bloodworms.
My female would not actively go after the food, she will sometimes takes in a piece and either spit out or swallow it.
I have treat with API general cure for any possible internal parasites.

I just wonder what are your experts opinion, should I worry about her health?
Thank you in advance for any suggestion.

Not taking food or barely eating for a whole month is definitely something to worry about .
Have you observed its poop for something unusual during this month ?
My first course of action for a non eating discus is elevated temperature treatment , going for 10 days with 34-35 C .
If I see transparent, white or yellowish stringy poop I add Metronidazole at 500mg/10 gallons along with my heat treatment .
