Guppies Not Feeding!

[Fish are friends]

Hi folks!
My small tank is a general community tank and is well established..i recently bowed to the wishes of my mother-in-law and got some guppies "cause they are pretty"... lol
Anyway lately the female ones haven't been eating the flake food which i use for the tank..the rest of the fish eat it but the females spit it out and are looking really thin..(their heads look too big for their bodies) any ideas what could be wrong??

Hmmm that is unusual. My fish go straight to the top as soon as I enter the room! lol ummm it might be that the other fish could be chasing them off when it's meal time and the females don't want to get beaten up everytime they want to eat.

The only other thing that it might be is that they have some sort of an infection? do they have any white spots or fuzzy spots on them?

Maybe they are stressed?

I'm not sure if i'm right or not I'm just throwing ideas out there

lol
