K First off... DO NOT put the female into the tank until there is a fair size nest already built... many females die if you put them in before the nest is built!!! Take it from somone with a high success rate!!!
Our last spawn was about 400+eggs!
K all you need to do is introduce the pair, you can do this easily by simply using a container that is plastic with holes in it, so that they share the same watter. I just used a breading trap/tank that floats in the watter near the top (you dont want a full tank either, just one that has about 4 - 5 inches of watter in it. Then when the nest is built (trust me youll know when it is, you can even put a styropome cup cut in half on the top of the watter like a cave and he will start the nest under that). Then once the nest is built carefuly dump the lil lady into the makes tank, be sure she has some place to hide from the male if she needs to (if she starts losing her fins, or he does then seperate them imediately). After you dump her in, nature should take its course, you will notice that she will come over and inspect the nest every so often until she thinks its good enough, if she does not she will not comply with his attempts to breed.
Another suggestion is not to have ANY gravel at the bottom of the tank, this is suggested only for a higher success rate, as the male may miss some eggs when they fall, if its in or on the gravel. Oh and once you notice that they are no longer "embracing" remove the female, and DO NOT REMOVE THE MALE UNTIL the babies are FREE SWIMMING meaning they can swim by themselves and are no longer sticking by the nest.
AND NEVER ASK WALMARTS FISH DEPARTMENT ANYTHING!!! THEY ARE NOT TRAINED!!!!
