mandarins are very fussy eaters unless hand fed from an early age, dont be tempted to buy one thinking you can feed it anything.
if you have lots of pods in your tank they will eat those first, and refuse to eat mysis etc.
imo do not try mandarins until you have at least a tank a year old (after cycling and all levels are 0 after stocking with a few fish, so your looking at 1.5 years to successfully keeping mandarins)
same goes for cleaner wrasses, unless you have a 200G tank with lots of fish they will run out of food to eat. (sorry was on a role there)
