In my experience different species take different amounts of time to go free swimming. HRP and cons were 3-4 days after hatching while midas, festae, herotilapia, and thoricthys species take about 5 days and have considerably smaller free swimmin fry. RTM's were at 4 days. My experience only and I understand temperature is a variable among others. My temp is always 76F.
good luck with your young.
