First time post... Quick background. I have had freshwater tanks since I was 13 but decided to go saltwater for the sole purpose of having Cephalopods. Besides Ceph's being the coolest animals in the sea... I am also involved in AI development and want to observe them for work purposes. With that said I have a healthy 55g tank started 4 months ago just for Cuttles and I ordered 6 eggs three weeks ago (expecting a 50% mortality).. well I received 12 eggs and all of them hatched in the last 3 days. TO top this off the Mysids I ordered turned out to be Grass Shrimp that seem to scare the little aliens. I ordered Mysids from another source but they won't be here until Tuesday. No one sells live brine shrimp around here so I bought some eggs today. I have read contradicting sources saying they don't eat for up to a week and others saying provide Mysid's from day one. So my questions are...can they wait to eat for 4~6 days and if not are the grass shrimp or brine shrimp a better choice?
