I had my shark egg for a good 3-4 months prior to it hatching.. Like I said, I could barely see the little guy when I bought him.. I actually had him in my 55g reef while my 150g cycled.. Placement of the egg didn't seem to matter.. He hatched during the day and yes the yolk was attached when he was born. It quickly went away, which leads me to my question.. He is now 2 weeks old, when and what do I try to feed him?????????? Oh yeah I have 2 magnum 350's and a 10g refugium. Also about 3-4 inches of <a href="http://www.purearagonite.com" target="_blank">pure aragonite</a>for substrate
