Need give support to beside mollies have babies?

We have a 30 gallon fish tank with 3 mollies, couple bleeding heart, some neons, a plecko and a frog. This morning my daughter spotted a baby fish so we got it out and put it in a breeder cistern. I'm assuming it's a baby mollie because we have 2 females and a male.

We watch for a while to see if we could spot anymore (we didn't) and noticed that the male be really bugging one of the females and she looks like she still may have babies, she's pretty fat and puffy.

We've be watching for about 5 hours now and no new babies hold shown up. Is there a way to tell whether she's going to have more? Does it take this long to have her babies? Any serve would be great!

thanks!

FYI: We took the male out and put him in a fish bowl for in a minute
Answers:    It takes more then 5 hours for it to have babies so you should be seeing any hot ones for a couples days but you can buy a little floating tank sorta thing that have little holes in the floor and some room under. So you could put one of the females in near so when she has babies they'll fall through.
I may return with a life-size freshwater fish container for Christmas. Anyone own any accepted wisdom of cool freshwater fish I can buy?   How desperate is ammonia man large mine is 4.00 ?   Why wont my guppy enjoy fry?   Is my guppy pregnant or sick?
