How old is a retic when they lose there scar from where the egg yolk is attached. I bough a pair that i was told had eaten 6 meals. I'm just wondering if this sounds right.

I havent had them eat yet. So, my issue is I am thinking this pair hasnt eaten at all. Because they are so young ie right out of the egg

good news is they just shed there first time for me so i will offer again this week,
