A fluid storage tank assembly is provided which includes a tank having sidewalls, a bottom wall and a top wall, and a support columns positioned between the sidewalls. The support columns blend into the sidewalls to avoid sharp corners and the sidewalls join with the bottom wall and the top wall along rounded edges to avoid stress concentrations in the tank. The tank is rotationally molded of synthetic resin, and is provided with a plurality of detachably mounted discrete legs which thread into recesses in the bottom wall. The top wall includes an indentation, and the indentation and the reception surfaces atop the support columns receive the legs of a second fluid storage tank stacked thereon. A bottom protector provided as a relatively thin sheet of synthetic resin material has a plurality of holes therethrough to permit insertion of the threaded shanks of the legs to pass therethrough for coupling the protector to the bottom of the tank.
