Definitely take the pistol out NOW! They've been known to take down small fish, and it probably wouldn't think twice about the cuttle. You definitely want to order some live mysis/etc. And the reason cuttlekid said to leave it in a breeder was not so you COULD feed it, but so you could watch it eat and monitor the amount it eats. Also, now that it's in the tank, who knows if it's alive- another good reason for the net breeder. Good luck!
