Care and setup tips

Before adding to any habitat, give all stones a thorough rinse. There are no coatings, so a simple cleaning helps remove dust. For secure installations, use aquarium-safe glue or epoxy to fix structures in place. Natural variations are expected and contribute unique character to each piece.
