I would like to qualify posting my method by saying that Winkin' and Blinkin' are the first cuttlefish I have tried to raise. They were purchased from Seacrop as new hatches, not eggs, and are now 6 weeks old, growing consistantly and appear healthy.
The first two weeks I fed a combination of new hatched brine shrimp (not over 8 hours hatched, providing egg sack nutrition but no digestion difficulties from shell development), live mysis (minimal quantities), copepods and frozen cyclop-eeze. After 2 weeks I introduced very small shore shrimp and continued with twice a day feedings of the Cyclop-eeze but eliminated the copepods and brine. At 6 weeks, I feed Cyclop-eeze only once a day and as many live small shore shrimp as they will consume in a day (usually 4 but sometimes 6 - I restock daily to ensure 6 in the net at the beginning of the day).
The cyclop-eeze is consumed by both the shrimp and the babies and is gone from the net in no more than 15 minutes (either by consumption or being washed out by the current). So far both my 5 baby Mercatoris and my two Bandensis are growing well with this feeding regime (the Cyclop-eeze remains in the net longer with the octos). There is not enough observation yet to see if the Cyclop-eeze provides true benefit but, so far, survival appears to be positively impacted.
