Type of sand really does vary with type, locale. SA/CA you would want playsand/poolfilter sand. Rift lake you would want aragonite, or crushed coral sand. It really does depend on what you want to do. No exact answer without first knowing what you want. But as far as live plants, you can have them if potted, or have the right cichlids. Discus do great with plants, Red Devils do not. Shell dwellers would be fine with plats, tropheus would not. Also when choosing the type of pleco, stick with the same area.
