the best way to breed them is to but to the male some things to nest under ... plants foam ... half cup and first of all u have to condition them with any live food or high protein food for a while ( week )
until u see a small white tube in the female like in this pic
then and after both be ready
male : build up a big bubble nest
female : ready with eggs
but the female to the male ... and watch them breeding and so until the male gets all the eggs from the female and start chase here away then take the female out and back to here tank .. start feeding here very well
and leave the male with the eggs until they hatch ( in few days may be 2 or 3 according to the temp. )
and after they became free swimming get the male up ,
start feeding brine shrimp .. or baby food ( what ever )
and cover the tank up as to keep the humidity as long as they are small to develop the respiratory system without troubles
and that is it .. wish u luck
