Got my first baby betta almost two weeks ago!

Of the 7 babies at the store this one had no real color and had a dirty cup, so I snatched the poor thing up. It's showing small signs of color now but who knows what color it'll end up! I'm mostly curious to know what type of betta it might be......and since I couldn't find any examples online of betta baby pics I thought I'd share and see if anyone else might have an idea. It's ventral fins are pretty long so I suspect it to be a male, maybe a veiltail. Until it grows up more and I can figure out more about it I've decided to keep it nameless.....thoooooough the temporary name Reading Rainbow has stuck some since the colors on its fins change from blue, green, and red depending in the angle you see it at =]
