The last small group dissapeared the 4th day. I did notice the first day when I put in arctic pods, they were rather large (little bigger than babies mantels) but some babies grabbed onto it and jetted around with it for a while. With the much smaller food such as cyclop-eeze and oyster eggs, I never noticed any feeding like behavior. The 3rd day is when I put the remaining babies in a breeder net and turned on the skimmer. When they were fed oyster eggs the skimmer was left off for an hour and a half.
