heh, mike just got to that before i did!
So, childrens play sand will be ideal if you can find it in an early learning centre or US equivelent
but my main point that i was going to comment on was the feeding of the cuttle, as Mike says.. they wont accept dead food until the are about 50mm or bigger... the best food for small cuttles is small live shrimp like crangon, palemon or amphipods like gammarus... not easy at all to get hold of in the LFS trade... but self collecting or getting in touch with people who supply foods to the public aquariums may be able to help there
