Just got a GSP and Toadstool "Colony" from Corals.com. My toadstool is about 1" x 1" and about a 1/2" stalk. It is the same size as a Toadstool frag I got from LiveAquaria before. The GSP are maybe a bit larger 2" x 2" but certainly not the advertised 3.5" x 3.5". Not worth spending the money on a colony when the frags are basically the same size. @Corals.com It is WYSIWYG but there it is only a picture, no way to confirm it's size on the website.
