I saw my mollie give birth - at least 3 fry - but I suspect there were others I didn't witness. She is thin now. This was Sat. night. Sunday she just sort of listlessly laid in the plants on the surface, although she did eat and she is still that way this AM. She ate a little, swam the length of the tank, went to the bottom and kind of flipped on her side like she was rubbing on the gravel and then went back to her perch in the plants on the surface. I read that female (and male) bettas are exhausted after the birthing process, but is it the same with other fish?
