try to feed only with the lights off.... If you see your tank when the lights are off then you should see the tentacles my brains are only active with feeder tentacles in the dark. When the lights are on the tentacles dissappear because they are harnessing light for food and growth when the lights are off they send out feeder tentacles to feed. I gave up on shrimp in my display a long time ago because they will snatch food right out of the corals mouth. One thing you may try is to feed the shrimps in your tank with a large enough piece of prawn so they are distracted then at the same time feed your brain coral. Mysis is too small for my brain so now I feed it pieces of prawn it takes it a whole day to eat but I dont have any shrimp or fish in the set up if you feed mysis make sure to feed about 10-15 pieces they should be able to eat it faster if it's smaller.
