A full fry drop is usually best described in terms of a few hours, not days. If you have a female dropping fry, expect her to finish in a very few hours. If the drop has been going on for a few hours, it may well be finished.

I am totally unable to determine from activity whether a female is done with a drop. Instead I will watch her for maybe 30 minutes or a bit more. If she produces no new fry in that time, she is probably finished.
A breeder will be fine for a week or two. You do not need a tank to raise fry. There are all kinds of containers that could be used. One of my favorite emergency fish containers is a plastic box like you might use to store sweaters over the summer. They will often hold quite a bit of water and are far cheaper than an aquarium. You will need to at least circulate the water in it with a filter or an air stone but can get away with doing lots of water changes if you don't have a filter for it.
If you get a simple filter with an intake tube on it, you can use a bit of sponge to keep the fry safe. I cut a slit in the end of a filter sponge made as a replacement for a power filter and then just slip it over the inlet tube. The filter sponge starts looking like this.

Once in place for a month or two it looks like this.

The sponge in the filter is on the inlet of the filter in my Heterandria formosa tank. Their fry are quite small. Even the adults are about 2 cm for a male and 3 cm for a female.
As a simple comparison, this is the sponge with an adult Heterandria swimming near it.
