I will! And I have concluded that the one in the back is a female (the one with a spot) and the one in the front is a male. The other little one (I want to stop calling them fry because they aren't, they are just small) is a female. Here is a pic of the male:
I know it isn't the best quality, but he is a male. This was just to show you guys his size. He's in a standard sized betta cup (it kills me to call these things "standard sized). The males in my 15 gallon are the size of normal adults. Is he big enough to be acclimated and put into the 15 gallon tank?
