While I was doing research on feeding my mandarin, I ran into a interesting thread somewhere around here. From what I had gotten out of the thread, people were saying blood worms, cyclop-eeze, and brine shrimp have no real nutritional value for marine fish. They will eat them, but do not get the nutrition needed for marine fish out of these foods. These and any other foods that cannot be found naturally in the ocean will not provide adequate nutrition and therefor should not be used for feeding marine species as a MAIN food source... IE..Dont bother getting your mandarin or CBB trained to eat these, as it does nothing for them on a nutritional value. Most people were recommending Mysis as the best food of choice for enticing mandarins, and I would imagine the same would go for CBB's. It said those foods are ok as a treat but not for a main food source. I dunno how true this all is, but its food for thought...literally

Figured I would just throw it out there to share what I had found. If it helps it helps, if not ohh well. :lol:
Also I have read that adult brines are not nutritional at all but freshly hatched brine with the yolks still attached are very nutritional. :crazy1:
As for my mandarin, I have had no luck training it to eat mysis. I have a four-line wrasse, for almost a year now, that is a very picky eater also. I have only seen the wrasse eat pods and the occasional peck at a mysis floating by. I've only had the mandarin a month or so now, but both seem very happy, fat, and healthy so I'm not too worried about it. I'll just add a bag of pods to the main tank every once in a while to make sure the pod population stays high, until the new sand bed matures.
