Maybe keep away from the squid, but with that many hermits you won't have to worry about any not getting eaten by the fish. My favorite is when I pick up a couple of kg's of live baby clams (vongola) from the fish markets for a meal, I always chuck a few into the tank, they bury them selfs into the sand, then get hunted down by the hermits, dug up, and they just sit there applying opening pressure with a couple of legs while picking at there little filter tubes, eventually they succumb and it's a food fest for all. It provides days, even weeks of entertainment\food.
