Clown eggs

[Treebeard]

I just discovered that my clowns have been busy when I was doing a water change today. They have a bunch of eggs stuck to the back glass of the tank. From what I read, it is possible to scoop them out of the tank when they hatch and put them in a nursery tank, but I have nothing prepared, and unfortunately I will be away for 3 weeks soon and not be around to take care of them.
I have a smaller tank, part of the same system that grows nothing but algae and pods, and was wondering if put the fry in the small tank if they would fend for themselves. There is a pistol shrimp and goby in the small tank which I could easily rehome if necessary.
