Whilst it may be possible to train this to eat frozen food, and if you are very lucky eventually pellets this fish will need a large tank (75g + but the bigger the better) full of live rock and a constant supply of copepods to survive, if the tank is large and mature with enough live rock and no other competition in the form of other dragonets, wrasse etc then the pod population may be self sustaining,otherwise you will need to add them very frequently.
How big and old is your tank?
