You do have to take into consideration how different cephs are from fish. They locate (at least cuttles and squid, less so with octopuses and nautilus) by sight. They smell by touch using their suckers (texture may also be involved). They eat using a beak to break off pieces and a radula to file it down to small bits to fit through their brain surrounded esophagus. Movement rather than smell appears to play a very important role with new hatchlings. Getting all this to work with bits and pieces will be a challenge.
I highly suggest splitting your first hatchlings if you want to try dead food when they first hatch. Live mysis shrimp have been the only consistently eaten food for the first month or so. There has been some minor successes with various pods and small shrimp but most attempts with other than live mysis have failed with no success with any form of dead offerings.
Another bit of undocumented and untested observation seems to indicate that second generation success my require live food. This is anecdotal and might be interesting to test while you are experimenting.
