Hi there! I'm new to this neighborhood, but I've been selling beach stones for fish aquariums on ebay for three years. The rocks come from beaches in the Puget Sound of Washinton state. I literally collect them one-by one. They're very colorful when wet: yellow, green, peach, red, lavender, plum. I've sold rocks to people all over the US, including Saipan and Puerto Rico! If you need aquarium rocks, please view my items and my feedback. Thank you!
