You can see the feeding tentacles shoot out and nab the shrimp. I've also managed to keep mysids alive much longer than I had previously thanks to the 5 gallon round bowl I'm using to house them, the correct salinity for their water, and feeding them baby brine shrimp. Thanks to Sara at aquaculturestore.com for the advice on mysids. I may do one more order of live mysids, so I can make sure they're all safely eating the frozen. The cuttles still seem uninterested or intimidated by the size of the shore shrimp, but those seem easy to keep alive. They're in a separate net breeder in the main tank, until we're ready for them.
