I was in my pet store the other day and saw a little fish (Maybe 1.5/2 inches long?) with brilliant colours, an almost-metallic blue body with orange stripes. He was sort of shaped like a bottom feeder, flat bottom and round top, but strangest of all was that he had fins on his bottom that were almost like feet. He practically walked around the floor of the tank! I'm wondering if anyone has heard of this fish. I couldn't get any picture, unfortunately, but I'm hoping someone recognizes my description? And yes, he was in a salt water tank, that's why I thought I ought to check here.
