There is no set minimum tank size , the problem with sharks rays and even some eels is that the requierments to properly house these animals are not meet by the standard aquarium. Some people are doing great jobs housing them in 180-220 gallon tanks . And there is nothing wrong with this. But they also have plans of upgrading even from there. Depending on which shark your interested in the tank size can range from 180 gallon tanks up into ten's of thousands of gallons in a pond/ lagoon. a small coral cat reaches about 24"+/- and a 180 is going to ok to house them for a while . now as you go along the lines and the sharks get bigger your going to need a bigger tank. bamboos will do fine in a 180-220 for a while but you should keep in mind that they need room to turn around and a wider tank is mandatory for a happy healthy fish. Eppullate's which are a bit bigger will also do fine but again an upgrade in the future is going to be needed.
Once yopu get into free swimming sharks such as lepords,bonets and reef sharks the tank requierments sky rocket into the 1000+ even for juvinals . They also requier special shaped housing to keep them from running into the walls . the tanks need to be more rounded on the ends. so this just circles the shark around to give the more open ocean type of feel for the shark.
Even for the smaller sharks filtration is of the most importance. these sharks give off a ton of bio load. and are very messy eaters. Skimmers , filtration should be rated for tanks bigger then the tank they are used on. Water quality is very important . You also need to ground out your tank water to help remove stray voltage thats in your tank. sharks are suseptable to stray current and even a few volts can cause them to stress out and not feed .
