Have you seen Paul B's baby brine shrimp feeder? That might be a bit easier than culturing pods specifically with phyto. Essentially it's a plastic container with netting over it with a hard plastic tube going up to the surface where you pour bbs into it and the mandarin et all can feed as the bbs move up to the light. Very effective, and baby brine shrimp is fairly easy to hatch, and cheap.
