Hmmmm. I wouldn't waste my time with the Artemia, even enriched (I've never had any success there, and it's a lot of work and requires a lot of space for near-zero reward).

There's a new deeper-water species of Sepioloidea (as an aside, I believe all New Zealand species of Sepioloidea should be transferred to a new genus) that we were collecting 200-350 metres, mid water, that we were able to transport by air in bags of water with a squirt of O2 in there. Mortality en route was zero, but they were mature (or almost mature) individuals when we caught them, they deposited their eggs within weeks, and almost all died shortly afterwards (no maternal/paternal care). Ours were fed on a mixed soup of amphipods, macro-zooplankton and mysid shrimp. The tank was 5000 litres, with ~ 30 individuals in there; I'm not sure what part cannibalism played in eventual mortality, but from memory the number of whole animals (dead) that were removed from the tank added up to the number of animals placed into the tank (so I don't believe it to have been an issue).

I've not tried it myself, given we have live feed available, but can you picture one of the garden-sprinkling systems (the brand available in NZ is, I believe, 'Gardenia') of a hose into which you screw the plastic uprights and then a tiny wee end piece that directs the water spray in the direction you want. Well, get the plastic uprights and then turn them upside down in your tank (so that you are squirting water to the bottom of the tank), and have an end piece that directs water in all directions. This generates an upwelling that suspends dead food (mysid) fragments in the water column (works a charm for seahorse).

I don't know if it will work for squid; mine (at 3.5 weeks old) will still not take dead food; it might be several months before I can wean them from live to dead shrimp/fish.

Did you get the Rossia in the end??
Cheers

I'll be ordering the Rossia this summer since Octopets doesn't get them untill then. For food I'll order from the Buy, Sell, and Trade forum.

I know I'll need a chiller but how cold is 9 degrees C in Fahrenheit? Also, is there any other place (other than octopets) to order Rosys?

Thanks um..., looked up here and it says 46.4F-50F. What brand of chiller would get my temperature this low? Where can I order one from?
Also, what is the ideal temp for Eupyrma Scolopes, and is there anywhere I could order one other than the NRCC? And are they pretty much the same as Rosia (more than one in a tank, little rock with deeper sand bed etc. etc.)?

I can't think of the temp the NRCC keeps them at off the top of my head... I can certainly check for you but it will be several days until i'm back there.

Pretty sure they'd do fine with a little rock and plenty of open space and sand to bury in. Also, I haven't seen any problems with more than one together.

they're cute little guys!

Sorry, no ideas about how you could aquire one.

Found the temp, 23 degrees Celsius which is about 73 degrees Fahrenheit.
Also, Paul (LFS manager/owner) may be able to get some.
Another question - will Eupymna Scolopes accept frozen food, or only live?
