yeah, 1-2 clay pots will work well. I like to remove the fry a couple of weeks after hatching and they're still rather small. Since the fry are usually chased into the pot to hide, I just pull the pot out of the tank and harvest about 90% of the feeders just like that. As Jason_S mentioned, cons are basically hardwired to breed anywhere & anytime, and if multiple cons are in the lfs tank you should be able to spot a pair or two already together.
