UM if you don't have a refugium or about 100lbs of liverock and copepods, amphipods, worms, aptasia, and other creepy things that they eat he will most definitly starve! Yea feeding brine will work as well as some other frozen foods, but for long term healthiness and happiness, lots of LR and a big fuge will do the trick. Keep in mind that you must not have any other fish in the tank that prey on the same things that he eats or they will be competing for food. I guess that would also depend on the tank size, larger is easier IMO when keeping one of the most delicate fish in the ocean! If you can't support him there will be plenty of folks on here that would trade or buy him from you!
Thanks,
