I was lookin at that guy too, his store is http://theifishstore.myshopify.com good reviews on AquaBid too. I was thinking about getting about 15 to start (5 of 3 different strains) at around 2" and let them pair up. Just have to pray there is one of each sex in each group. I can share my spreadsheet if you like, it has pricing and links to different breeders and suppliers.
that would be awesome. yeah i was thinking something similar, with 5 of each breed the chances of not getting at least 1 M or F should be fairly low. something like 1/5 for each strain or .8% on the entire group. Not sure how picky you are but there are also a chance of interstrain pairs and my research has shown that you can force a pair if need be.
