She is one that I got for the well water tank. She is pretty round, that spot is much darker on her than on the others. I just had them scoop some up, and she was pretty much grey when I put her in the tank, but by the next day, the tail had darkened up, and there is some iradescent blue/gold in the center of it that doesn't show here. They are amusing fish, very, very different from bettas, and Neptune

is NOT amused that their tank is next to him!!
So far the well water has been good, and I have also heard from guys on a forum in Winnipeg who live in rural areas and are on wells, and all use their well water with good results.
It would be pretty funny if my well water experiment also made me learn how to deal with fry, but I saw a couple fry in the tank at Walmart, and they are so cute!!
Waiting for the mail! Val
