Just received by first cluster (total of 9) and they have hatched 4 days ago. My question is how long before they start eating live prey? I have put some copapods in with them and nothing, next i tried fresh brine and nothing is there a egg sac they absorb before the eat live? I have 1 adult that is a year old that i got when he was eating small ghosts ut these little guys dont seem to hunt at all. I appreciate any advice from seasoned cuttle veterans.
