Pods.:yes:
A very established tank, with an established colony of Copepods, Amphipods, and Isopods have been the more successful habitats for these fish. Some will accept other store bought foods, but it is not worth risking if you don't have any pods for them to eat while you are trying to get them used to the store bought.
BTW: even if you can get them to eat store bought, that doesn't mean it holds the proper nutritional value.
