No offense was intended at my end, I apologize if it came across that way.
I have pretty strong opinions about keeping sharks (in general) in captivity. There are a few here that do so with great success (Andre Garcia is one).
The shop I worked at many years ago used to get eggs in occasionally. Sometimes they would die before they hatched, and most of the rest died shortly after hatching. So to that end I'm a bit jaded when it comes to that particular practice.
As a parent myself, I just imagined how my kids would have felt in that circumstance. I wasn't at all trying to be critical of your parenting - just offering up a possible outcome.
