Was in Pet Smart tonight and they had several male and female bettas. I purchased a female because i have such a big compassionate heart and she was swimming around in probably less than an inch of water. She was not the prettiest but i just felt she deserved better. Now she is happily swiming around in a 55 gal tank and is looking very pretty now. But for the origial reason I posted, what is it that they put in betta water in the pet store that gives it that blue tint? just curious, sometimes it makes it very difficult to pick out a fish because you can't really determine the color and how it looks beacause of the blue water. just wondered if anyone knows.
