I have 5 grown mollies and a couple of small fry hiding in one of my plants. they were born last night some time, as hard as i look i can only see those two so i assume the others were eaten, i'm not sure which one of the adults gave birth but i noticed a particularly chubby one is being constantly followed by another who appears to be "sniffing" her rear end. might this be the one who gave birth and if so, does she have more to drop or is there maybe some other reason for this "sniffing"? i've noticed a couple of other ones getting close enough to this one to check out her backside also. any idea what might be happening?
