Unless I have my species mixed, these only spawn a few eggs each year so raising enought to sell may be a problem. Before they became a major conservation topic and were reasonably priced, I fed the red shrimp to my seahorses (the supplier has their own ponds but are facing restrictions anyway). There is a lot of controversy over using these as feeders and I hope you are successful getting the permits and raising them for this purpose as they are a great size and the red color attacks even the pickiest of horses. The color, however, would seem to be a problem for cephs.
