Get a huge refuge with load of live rock and seed some pods.
I have one that feeds on frozen brine, I currently use brine that has been gut loaded. But I will tell you it get tedious making sure all the other fish and my one lone fire shrimp are fed first. He eats so slow that even the clean up crew get on the action. Which of course if you are not careful about is going to add alot of nutrients to your tank.
If you want to try to get him started on frozen. Take it to a smaller tank, feed some live brine, then slowly add some frozen brine over multiple feedings. Mine won't eat Mysis or pellets, but I haven't had the chance to try him on either yet. Seems that it takes time for them to realize it is food. Take a turkey baster and gently blowing the frozen brine seems to help stimulate the feeding response.
I have read people whom try to feed with store bought pods, and it quickly gets expensive. They are constantly feeding. If you buy the pods and start a culture that is going to be more feasible, but still time consuming.
Good luck.....
