Got it about a month ago it was about half this size, now it's about an inch and a hlaf wide and 2 tall when full expanded. Pic isn't great but its the best I can get, The silly thing decided to plant itself on the bottom/side of a pwoer head. Good thing there's a sponge on it!!!:lol:
They have tube feet like a starfish, well atleast this type does anyway, don't know about other cukes, It climbed right up there when I got it, I moved it when I cleaned the tank once and it climbed right back to the same spot.
