Should I have fry by now?

[ScottishFish]

I have got 6 mollies in my community tank at the moment, 3 jet black females, 1 silver female, 1 orage/black female and the stallion of the tank 1 jet black male. All the blacks I added together around 8 weeks ago, and the two others around 6 weeks ago.

The lfs I buy from does not seperate males and females (he does with guppies but not mollies, wierd) so they all came from mixed sex tanks.

I know livebearers usually are giving birth every 4-5 weeks but so far I have no fry, I have watched the male mate with other females, he has been doing it since the day and hour I got them. I do have a very densly planted section of my tank with a micture of elodea and cabomba, which to me is a haven for fry.

Problem is I have yet to see a single fry. I have got a few of ideas to why this might be.

1. I have a big healthy very peaceful but very hungry firemouth.

2. My khuli and weather loaches love hanging around up in my cabomba and elodea and are therefore dining on them.

3. They are getting sucked into my filter (doubt this though)

4. The male is sterile so no babies. (but they came from mixed tanks so I thought there might have been one that was pregnant)

5. My bolivian rams are eating them.

I did buy them with the knowledge that most probably will get eaten but with 5 females I have not seen a single fry, like not even a glance at one. I would have thought there would have been at least 1 fry survive. Any ideas anyone?
