According to published information, the fry take 5 days to absorb the yolk sac before they become free swimming. Yesterday was day 5 post-hatching, and when I checked this morning a few minutes ago after the lights came on, I see that the 7 fry are spread out around the tank whereas for the past 5 days they have remained basically in one corner (5 of them, the other 2 I could never see). So they are obviously moving around the tank today. They still appear to be rather motionless, but if I sit and observe them for a longer period I should see them "swimming". They are about 1/2 inch in length now, very thin of course, and hanging on plant leaves or the glass.
I've let the direct daylight and sunlight hit this tank for the past couple of days to encourage algae, as they require soft green foods at first. Feeding the fry initially is said to be the trickiest part of the whole process. I can't see there is any need for me to start polluting the tank with decomposing spinach or something, there is a lot of natural algae which is after all what they would eat in nature.
