The one I really like right now is one of the big ones he's dark bodied and is starting to get a little bluish iridescence to him. I know its too early to be looking at fin structure but I'm really liking his fins so far.
They're averaging in size of about .75 centimeters right now... Maybe a little more or less. Basically they're almost as long as the width of my finger.
I noticed some of the fry have smaller fins than the others, particularly in dorsals... I wonder if those will turnout to be female. I guess I'll know in another month
