Okay, so went to pet city, not quite 2 tanks with at least 100 Festae but 1 tank with 4 around 1.5" and another tank with around 20 that were about 3" didn't buy any, gunna hunt the forums for better deals, probably gunna buy 10 to look for pairs.
Mate those tanks were full they do sell quick.
Good luck finding any on the forums i never see any come up for sale but you never know your luck.
Exotic Aquariums at Rocklea are the other good shop for CA/SA fishies.
