I found this Dan
''I use Tahitian Blend from Brine Shrimp Direct to feed them with all the time so they are always gut loaded and I can take some out, rinse, and put in the tanks at any stage/time of growth.
For specifics I have Selco, also from Brine Shrimp Direct which is the fatty acids or Huffas as some know it.
For high protein levels I use the high grade spirulina from Jehmco, about 95% spirulina compared to normal spirulina which is usually around 45% spirulina.''
