Mandarins do not need tank volume to suit their activity level like a tang, the restriction has always been due to their dietary restrictions. These are not mid or upper column dwelling fish, they 'climb' the rockscape like mountain goats. Biota Aquaculture Mandarins are raised on frozen and dry and do not 'need' a live food source. Live food is almost always avail to supplement/restock a tank/refugium as well.
All that said the mandarin is not a beginner fish and setting a 1 year goal to age a tank is a good idea for most who are new to marine/reef. Keep stable tank parameters for a year and one should feel comfortable taking on the more difficult challenges
