You can try the auctions on aquabid but you're going to pay through the nose for shipping. I just got 6 Sterbai off there for $36 plus another $36 for shipping. Still a bargain compared to paying $14 apiece from liveaquaria.com plus $40 shipping. You might want to look at corysrus.com too.
lol.. i looked on aquabids and its the same people from corysrus.com.... they run the shwartzi at about 4 bucks plus shipping..... so im goign to ask my friend whoe is head of aquatics at petco and see if the can get some in for me... and ill take 6 if they are cheap
i bought some at wal mart about 8 years ago for a couple bucks apeice. i had them for 6 years. they were some of the hardiest fish i've ever come across.
