If your female has the white patch on it, I wouldn't neccisarily breed her... I mean I'm no expert but I wouldn't want to take the chance of that going onto the offspring! If per say it was related to genetics.
I do agree with Teeney, it takes A LOT of work to raise healthy offspring.
I'm not sure if anyone else mentioned this, but that bamboo in your tank is not fully aquatic, it will eventually die. It can live in the tank but the leaves must be out of the water to do so.
