So I found this poor little boy in walmart today. He was in the dirtiest cup there that still had a live betta in it. I wish I had taken a pic, but I did measure the ammonia and it was at between 3-4ppm.
So I talked to the manager, showed him all the dead betta's on the rack, and explained that he needed to take better care of the fish in his store, that its horrible he lets customers see them like this, and that I wanted this one but I don't want to pay full price for one that will probably just die within a matter of a few days. SO, he let me take him home for 50cents.
I got him home, tested the water, i added fresh water to his cup at the same temp to cut down a little of the ammonia, and then acclimated him to his new home. He was a little iffy for the first 4-5 hours, but he started pirking up when he finally noticed the male next to him, so I figured I'd try to feed him. It was so sad to see how he looked at it at first, like he didnt know what it was. Then he took his first test bite, and he was on a mission after that.
Here you go!
Looking around

What is this??

Hmm, doesnt taste so bad!

Uh oh!!

Finally Satisfied!
Just want to mention, yes that is a .5 gallon. I am QT'ing him in this until I get all the 2.5's I ordered from petco in the mail in a few days.
EDIT:: Should I be worried about that white stuff on his chin? he doesnt have it anywhere else on his body so I'm not sure if its just opaque scales or what? Its not fuzzy or anything, just white like you can see in the pics.
