Create shelter, planted pockets, and unexpected details within your aquascape with Black Lava Rock Caves! Made from porous Black Lava Rock, each piece features one or more openings that can be positioned as caves for aquarium livestock or incorporated directly into your planting design.

Turn an opening upward and treat it as a small planted pocket by adding aquasoil and aquatic plants for a Wabi-Kusa-inspired look. Lava Rock’s textured surface provides natural grip, making it a great option for stacking and building formations with planted pockets layered in at different heights throughout the scape. Use mosses and rhizome plants like Anubias or Bucephalandra to fill larger gaps and create a continuous, grown-in look. Alternatively, keep the openings exposed to create shelter and swim-through areas for small aquarium livestock.

Best For
