I'm really sorry for your loss.
It really hurts to lose a fishy friend even if you didn't know him for very long.
But think even though he didn't make it you gave him the chance to die a peaceful death in a nice warm tank knowing someone cared about him, instead of a cold and dirty little cup.
You should feel good about what you did, because it was really a gift that you gave him and I totally commend you for that.
I went through a similar situation with a little betta that I named Charm, he also only made it one night and even though it hurt to lose him I was still happy I gave him the chance to be at peace.
Sad as it is, sometimes they are to far gone to help and all you can do for them is to give them the chance to be at peace in their last hours.
You did this for him and I'm sure he really appreciated it and knew that you cared about him.
If you feel up to it you could go back to the store and let them know that he didn't make it, they should give you a refund or replace him.
I know it's hard but I would go back so they get the idea that it is not alright to sell sick fish.
