Hey,right after they lay the eggs,i remove them and place them in a seperate tank[the ones with the plastic cover,you can often find these and are imexpensive]
Then,I would remove the cover,and cover it with something translucent,eg tracing paper.
Then,place a low watt bulb above the tracing paper,then turn it on.This will simulate the moon,and also help the fry to find their food,which in this case,is artemia or baby brine shrimp.
Just a heads up,the eggs will hatch only at night,so watch out for that bit.
Feed them frequently,then transfer them into a larger tank when they have grown in sizes.
Continue till they have reached Adulthood
Cheers
