According to what I have read about dalmation mollies, they sometimes get a blue hue to them when they are happy. I want one so bad!
LOL. not quite. They have to be happy for awhile and properly taken care of. Kind of like how a betta builds a bubble nest when its happy and healthy, dalmation molly's get a little blue (ironic huh? lol).Like a natural mood ring effect!? That is cool! I may have to get one of these too.
