Nope. They all need plenty of swimming room and other fish don't resemble them that are small so you can't have the "shark" look unless you have a shark. And many people say they need a 180 gallon minimum. Not true. 6 feet by 2 feet is much to small even for bamboos. They reach about 42 inches and couldn't turn around in a tank that size. I have been planning a shark tank for years. If I ever do it, it will house two bamboos. It will be 12 feet long and 5 feet wide, I have gotten many quotes and it's not to bad. The only really expensive thing would be the skimmer, filter, and chiller.
