Here's some pictures of my shark for you. He is 2 1/2 feet long. We did not hatch him from an egg though, he was about 15-16" when we got him 3 years ago. At this size he is constantly re-arranging my rock for me, and harassing the other fish in the tank. A few nights ago he attacked and killed my 4-5" female saddleback clownfish. He caused fatal damage in only a few minutes, was giving his best impression of a Great White. I was less than thrilled to see this side of him, of-course my husband thought it was cool. I took some pictures of my deceased female clown "Lilly" to prove that these sharks are capable of inflicting considerable damage.
I have a female Bamboo Shark in a 125 gallon pond in my garage right now, she is only 18", and will have to be atleast as large as the male before I can add her to my tank, and try to breed them.
Congratulations on "dipping your feet" in to the sharks, they are very rewarding and fascinating!!
