(Milwaukie, OR)  --  The Portland Aquarium in Milwaukie is set to shut down in February.  Marketing director Susan Elcox says the aquarium has outgrown the building, which is scheduled to be demolished after the aquarium closes on February 15th.  She says it's possible the Portland Aquarium will resurface in another, larger location, which hasn't been determined.  Aquarium director Rober McBee told KOIN-TV most of the animals will be transported to one of the company's aquariums in Austin, Texas.
