Well i am getting a new 75g long tank this week and i really want a shark. I am just wondering if there are any species of sharks that i can keep in this tank. I have been looking at Bamboo sharks, but i think it will get a little too big for the tank. Does anyone know of a species that stays about 2ft or less. Also are they any small rays that i could get. I know that freshwater tea cup rays only get about 18" are there any small saltwater rays?
