I had the most success with my mandarin by feeding several different frozen foods. I started with frozen cyclops, then moved up to baby brine, big brine and then mysis. I still feed an assortment of frozen food but she has been eating pellets for over a year now so I don't worry nearly as much as I used to.
And yep, they look like they are dead when they sleep. lol My fiance woke me up one morning to tell me the mandarin was dying, took a look and she looked really bad. Luckily I didnt freak out cause I knew already but she gave him quite the scare. hehe
Good luck !
