Need info about saltwater shark and tank build

[ghosttruck]

I want to get some informer about other people shark tank for black tip and other.

I want to build a shark tank and want to know how big the tank should be like how long and wide and where to get a shark or who might have one.
The shark tank is only going to be for small black tip. And when it get bigger I would like to sell it. To some one in Calgary.

And I would like to see your shark tank to get some idea and that

Hope to here from you
