Yes I don't think she's done yet!
are you sure the fry is hers? You need to move them out of that container. They need heat and especially for the fry, unless you have a room temp in the mid 70s to 80, they could die... Even the three gallon bucket with a heater is better then a Tupperware. And the mother will eat her own fry, just so you don't have any surprises...
see if you can get a breeder until you have something better. If you want to save the fry, a breeder is a good idea. I highly recommend setting up a fry tank. But until you can do that, get them some heat in the bucket or get a breeder
