Well, approx 30 hrs after being taken from the Walmart nightmare, he couldn't hold on anymore.
I know Hindsight sucks, but I wonder if the better course of action would have been to have purchased the "aggressor" Betta and leave the weak behind? Maybe I could have at least saved the community fish that i'm sure also lost thier lives last night.
Lets hope my complaints to Walmart will actually make a difference and no Betta fanciers, any where, will ever have to intervene in this type of situation again?!
I can wish can't I?!
Thank you everyone for all your help, support and kind words.
