what i do is feed up both fish for about 2 weeks , lots of live food / frozen bloodworm etc , set up a small tank just a degree warmer than there normal tank, place a strip of polystirine about 2-3cm wide accross the front of the tank for them to build a nest under. also place a few things in the tank for the female to hide in until the male has finished building the nest.... add fish and wait , withing two day there will be a nice nest with lots of eggs in it, 2 days later lots of very little fry. After there have done there thing i remove both parents, add a few leaves of crushed lettue for infersoria and a few drops of number 1 fry food. sit back and watch
Has workd every time for me
