Now I've seen a lot of betta fish that people call turquoise-something-fish. I see those fish indeed have the color of turquoise. But then I found this really cool fish that has the color of a real turquoise stone. And it also has hey-this-is-my-area attitude towards other fish. Not dashing around, just staying calm with its fins wide opened and its eyes right on the target. And so we have a name for him: The Cool Brother.
