you need 1 male and 1 female... lol.. and then you put them in a nice tank ... lower the water level - and then put a small piece of plastic film on the water level so the male can make a nest there. that way you can see the eggs too.
then one fine day when you see a nest and a preggo female, and the male beats it up and twists himself round her and all these eggs come pouring out... then you have bred them! :bounce:
once the egg laying process is over, and the male has thoroughly bashed the female for good measure it may seem, take her out and leave him in there to keep picking his eggs up and sticking them in the nest. when they start wiggling you can remove him, but i usually leave the male in there for a day or so.
hope this helps :lol: :bounce: :bounce:
