Am having difficulty on finding a good sand to use. I am partial to the CaribSea Fiji Pink but none of the local stores seem to have it in stock. Is it better to have the LFS special order or order online and if online what is the best place to order from for the best price. I am interested in keeping a jaw fish and/or a goby & shrimp combo. Would the Fiji pink suit them well or are there better more cost effective options that have a lighter sand color? The LFS seem to want to always steer me to the live whatever they have.
