Whatever size the frame is, the size of the page inside it is determined by that page's design and amount of content. Assuming it's the Tropical Fish News page, how about having less news? But honestly, why worry about it, your visitors will decide whether they wish to view it all or not.
Ah, there lies my problem. The page is not reduced in size but is instead simply placed in the smaller box forcing users to scroll left & right & up & down. The size of the text does not matter if the whole page were to be shrunk down as this is only a draw to the trading board pages of the site. The linking page that I really want there is quite large.
