I know it wasn't on purpose, but you waited too long to start experimenting with frozen food. Now that the mandarin is already thin it has a much higher chance of starving on a diet of frozen food. If you have a friend with a lot of established live rock, I would put the mandarin in there until he fattens back up. After that I would try the frozen foods.
If you decide to keep him in your tank, definately spot feed him every day and make sure he is eating. I would also supplement the frozen food with live brine shrimp (posibly coated with nutrients if you have the ability).
