Yes, they do change colors. Sometimes when you buy them they look pale and when you get them home in clean, heated water, they will change colors. My pink female was a pearly looking white when I got her, then she turned pink with maroon fins! lol

There IS a reason. you guys snatched up MARBLES. Whats a marble? A marble is a betta that changes its color as long as it's alive.
The first marbles were white bettas with black bumps on them that appeared and dissapeared and reaapeared on the fish's body.
Marbles change because of what is known as the "Jumping Gene".
Now marbles don't have the bumps and can change from red to purple and any color they darn please
. Here's some pictures of a marble. This is the SAME fish:
