I get most of my stock from other hobbyists because the rarer livebearers that I like are not available at the LFS, ever. I also sell my breeding surplus because the rest of the club hobbyists have nowhere else to get them. The club auction is an exciting time for me. I take stock of what I have on hand that I would not mind passing along and then go to the auction and look over what is available that I don't already have. My main focus is a group of species called goodeids, but recently I also picked up some Xiphophorus montezumae and some Xenophallus umbratilis at a club auction.
