Fry grow-out tank suggestions

Tonight I setup a fry grow-out tank for my swordtails. I started my current planted tank with 6 swordtails (3 female, 3 male), and currently have the 6 adults and about 15 juveniles in my 29. The grow-out tank is 10 gallons, bare-bottom with a sponge filter (cycled by placing it in my HOB filter for a week). It is decorated with a plastic castle, the plastic tube from my sponge filter (too tall for tank), and most of the Hornwort from the 29.

The current inhabitants of the 10g are 1 swordtail fry (hitchhiked in with the Hornwort), and snail hitchhikers. The temperature is 76 degrees.

My questions:
The only lighting I have available is a desk lamp with a 60 watt bulb. Will this be good enough to grow the Hornwort (or keep it alive)?

How to grow algae in the tank? Will this help the fry to eat?

How do you tell when a female swordtail is about to give birth? I have two females who are looking pretty fat right now.

Any other suggestions would be appreciated! Thanks

The incandescent bulb would probably keep the hornwort alive in a 10g, and you would also probably end up with a lot of algae due to (likely) improper spectrum. Ime, for livebearers, I always just fed the fry ground up flakes and other freeze-dried foods and they were fine. The fry are fairly big by the time the mother gives birth. I think they'd be large enough to eat baby brine shrimp (frozen or whatever) from the get-go.

As far as I know, you will see a dark spot near the female's vent, you may even see little fry eyes when she is ready to give birth. Are the males following her closely?

About the light, if it were me, I would pick up a 15w 6500k spiral CFL at walmart that fits your desk lamp. It would grow the hornwort much better and, to me, would keep the tank much healthier. Hornwort is a great oxygenator, but if it isn't growing well, it isn't benefiting very much. I think GE makes them.

Thanks. The two females I was talking about are looking pretty close to giving birth, as in less than a week. One of them is solid black so its hard to tell how close she is. The other one is white and red so it's easier to tell with her. The males aren't following them around any closer than normal.

Edit: Tonight I saw one of my males chasing the two pregnant females and a few others. I also saw two juveniles rubbing against each other. Are these examples of breeding behavior?
