I would name her Rosie, and as for Wal-Mart, you are right they do not know how to care for fish.
I went there one time and all of the Betta cups hand their lids shut tight with no air holes.
As I proceeded to lift it up a bit so they could get some fresh air, an employee spotted me and shut them up tight and said they breathe in the water...
Hello?!?!? Do you see any air bubbles in the water?
Anyway, the Walmarts in our area, all 4 of them no longer carry fish of any kind thank goodness! They used to keep their tanks sooooo cold as if they were in a cooler and all the fish were listless. *shakes head*
