It can realy take a while. Thats depends on how long the babies stay in the eggs. If the yolk sack is small they need a longer time to start eating. If the sack is big they'll don't need such a long time.
If they start, you can nearly feed them every 6h so they grow fast. My 2" big cuttle eats 5-15 ghost shrimps every day (!!!)
hi after a mad day i managed to get hold of some very small ghost shrimps tried a couple and some cuttles are now feeding i think it will be a couple of days before the others start as they hatched later thank you all very much for advice .
i will keep you up to date
