Cat shark question

[Mr_Banana_Pants]

I recently bought a marbled cat shark egg. I can see the little guy doing somersault in his egg, and a fairly large yolk sac. Is there anything in particular with the egg in my tank? It is currently hanging from a seaweed in an area of moderate flow. He will be in a 75 gallon tank in the beginning, planning on upgrading to a 300 in the next year or so. I'm also curious if anyone has any ideas with helping the little guy out of the egg as the yolk Sac depletes, and any tricks to get him to start feeding after he hatches?

Don't help him out. He will come out on his own. He will take up just about all the space in the egg.

Agreed. Let him come out by himself or you can kill him. Also that 75 may not last as long as you may think. I have seen them grow fast and a few slow.
