Hmmm, I don't know if they are captive bred, but I will check tomorrow with my lfs, The "fish guy" wasn't there when I purchased them but he'll know where they came from. So far I haven't noticed them eating anything, I have been putting in a little frozen mysis and these small frozen copepods (I forget the name) but they are red. I'm guessing that probably means they are WC but I will absolutely find out.
