WIO Hole Stone Nano Rock brings distinctive natural perforations, warm gritty character, and functional sculptural interest to nano scale — a sedimentary stone with characteristic holes of varying sizes, perfectly sized for nano compositions where unique texture and natural shelter are the priority.

Hole Stone Nano Rock carries the same uniquely perforated character as the full-size Hole Stone — natural holes of varying sizes that perforate the warm, gritty surface, creating functional caves and shelters for small aquatic animals and perfect anchoring points for epiphytic plants and mosses. Even at nano scale the perforations are striking and functional, adding a natural and artistic touch to any small aquarium or vivarium.

Sized between 3 and 10 cm, ideal for nano tanks under 40L. May raise pH and hardness slightly; regular water changes keep hardness under control. Pre-washed and ready to use.
