So COOL isn't it seeing them hatch, very EGGCITING ! 
Leave them in there until, you see them walking around pretty well, if on hatches like this afternoon, maybe by later tonight he could be moved.
Thats what I do anyway, when they atart to still and seem to have their footing so to speak, they go into a tank.
Be prepared though, it usually takes a long time for them to hatch, sometimes you will see the head, and it wont be completely out till hours later, even the next day.
They have to work very hard to come into this world. 
Just as reminder, do NOT help them, they come when they are ready! I wish you all the best with your little ones!
Hope to see them soon!
