Well sad story but the shark ended up dying. I had him for almost a year. I was going to buy a bigger tank for him when he needed it. I think I am going to buy another egg eventually. It was really easy to hatch. I took a razor blade when I bought the egg and scrapped off all the seaweed on the outside of the egg so I could see clearly into the egg. It was pretty cool because you could see the shark with his ball of food attached to him. Once the ball got down to being really small pretty much completely gone, and I had the shark egg for a month and a half, I had a friend cut a hole in the egg. He cut the sides where they meet. The shark eventually swam out. He lived for a year and died. His diet consisted of frozen squid chunks, and live rosies. I would use a feeding stick because when he snapped his teeth you could hear it outside the tank.
