Kelberi for me.
All tems and azul kinda look alike when they get big respectively. You already know how these two turn out to be when they get big.
With kelb, you never know. Some may turn on like stunner while other may look plain.
Personally, I will go with a bunch of fancy wild kelberi (Ceara) or CB kelberi fry whose parents were awesome looking.
I like the vertical striped piquitti half way down on the first page of the thread. If you could get that striated type pattern, with the colors of azul and kelberi, THEN you have yourself a winner in my humble opinion.
