From what I understand Mandarins graze pretty much constantly. What you consider a lot will probably be mostly gone in the first week. If you want to have one you will probably need to culture pods in other containers and add them to the tank or it will slowly starve to death. Make sure to get Tisbe copepods as opposed to Tigriopus (Tigger) pods.

As an alternative you could get an ORA captive bred target Mandarin. They raise them to eat pellets and frozen food. ORA may have Blue Mandarins available now again as well, but not last time I checked.
