Myopia, I just got off the phone with the LFS I spoke of. Long story short the tank is a 250 gallon reef set-up with 1 nurse shark, 1 bamboo shark, 1 freycinet epaulette shark and 2 marble cats. He said the nurse shark will get very large over time, and he has plans to move him to larger tanks, and even has a contract with our local zoo to take it when it gets too big for him. He also said that he would like to know where you are from, you may have some good places to talk to around you that he may know about. He is easy to talk to, and not overly critical (like many of the yahoos on this site) and if you want his info to speak to him, drop me a private line at my e mail and I will give you his info. Good luck, BB
