"The only item Limato, who pulled down a base of $5.25 million before getting the bum's rush, has re turned to claim was a bowl housing his half-dozen exotic fish. 'ICM refused to build him a custom aquarium, which he de manded when ICM first moved into their new MGM Tower offices in February,' noted the insider. 'He had at least one blowfish and named them all after his old assistants. If one ever died over the weekend, his assistants would replace it with an exact replica so Ed would not know.' A call to Limato's new office at William Morris was not returned." We wonder if Limato is aware of his new agency's disturbing history of fish murder. He might have to hire an assistant just to keep his aquarium safe from malefactors. [Page Six]
