I have a Psychedelic Mandarin that has been in my 60g with about 80 lbs of live rock for about a month now. He is a mysis shrimp pig and is happily getting quite fat.
I got mine from Oceans where they had a few of them. I had them feed the tank some mysis to see which, if any, were eating prepared foods and a couple of them took it right away (one of which is in my tank now).
To play it safe I would ask the LFS you plan to purchase from to do the same. that way if your pod population is not sufficient or dwindles at least the fish will be supplementing its dietary needs with the prepared food.
Good luck, they are a great fish
