i fed my spiney boxfish 2-3 times daily (ok thats how often he eats lol but i feed him purposely once a day he loves the pellet i give my other fish lol
I feed him squid, krill ,silverslides,shrimp,clams,crab legs( once in a while)boneless chunks of fish, scallops,they also love to chew on crushed coral not only keeping the substrate clean but to help file the teeth.
