Ancient StoneAncient Stone is a beautiful aquascaping stone that is comparable to other popular choices such as Manten Stone or Yama Stone. This aquarium rock features a varied color palette of grey and brown tones. The general shape and style of this hardscape is ideal for Iwagumi layouts or nature style planted tanks. It works beautifully alone or as a base for aquarium driftwoods. One of our favorite stones as of late!
