About a month or so ago I had all of my cuttles die off somewhat mysteriously. I couldnt trace the cause so I got two juvenile Cuttles shipped to me. They had been doing well, untill yesterday, one of them died. I can't be 100% sure but I think that the cause was salt water feeder fish that I got from Paul Sacchs. The first dieoff occured about a week or two after I added the saltwater feeders. First one cuttle died. Then another, then the rest. I was out of town and came back to a skunked tank and only one fish left and two cuttles. One cuttle died a day later but the other Cuttle lasted for a week or so untill she ate a fish. Now, I've had these two new Cuttles for about a month or so and they have been doing great untill the last fish I had in the tank from that batch was eaten about 2 days ago. I noticed because I was hand feeding the fish flake in the mornings and all of a suden he wasnt there anymore. The next day a Cuttle was dead. No signs of fighting or injury. Just dead in the bottom of the tank. Anyway. I wanted to warn everyone about this and share my experience and hypothesis. I now believe live shrimp and fiddlers to be the best bet for food for Cuttles. Atleast with other inverts you can quarentine for a couple of days to make sure they aren't poisened with heavy metals or copper that could kill your cuttle.
