Banded Cat Shark trying to hatch too early?

[Kati]

Hello! Today, I impulsively bought a banded cat shark egg for my 75 gal (I know, he will outgrow it soon) thinking he still had about 2 weeks to hatch (his yolk sack is still the size of a marble?). Well he got him all set up in my tank, and for the first several hours he with rather inactive, and now after about 9 hours in the tank, he is pretty clearly trying to push out the "opening" in the egg. He has been at is for about 45 minutes now... and I am just not sure what to do with him if he hatches early? is this even something to be concerned over?

Let him work his way out as he pleases. If he hatches with any of the yolk sac still attached to him it should be used up within about the first week. Give the shark time to settle in before trying to feed, as the yolk sac provides enough nutrition for a while after they hatch.
