I agree with Mark. I kept my target and green Mandarins in isolation for about a month while I pounded them with foods to fatten them up. They were very thin when I got them from the LFS. Besides the pods in the tank/fuge they also are adult live brine shrimp. I eventually got them eating frozen enriched brine and mysis by mixing it in with the live brine when I feed them and now they will accept frozen and formula one pellets. They seem fat and happy and have grown pretty fast.
