Black Tipped Reef Shark Question

[KISSfn]

Just finished watching "Tanked" on TV. On the show they built a 2000 gallon aquarium and stocked it with a Black Tipped Reef Shark, a Nurse Shark, some Rays and numerous small fish. Plus the tank had a bubbler. I don't know much about saltwater fishkeeping so I have a couple of questions. What is to prevent the Black Tipped Shark from eating the small fish? I thought bubblers in a saltwater tank were a bad thing? Any help much appreciated!

bubbles are not a bad things. Some people use them for "show" or "glimmer" really. Oxygen in water is good! Most people don't like them though. As far as eating, they eat squid and feeder shrimp etc. Not really big fish eaters from what I have read...
