## Long description

Polished Tiger II stones from NB Minerals are natural decorative stones sized 30–50 mm and supplied in a 5 kg bag for use in aquariums and terrariums. These smooth, polished pieces provide an attractive hardscape element and can be used as substrate components, accent stones or to stabilise plantings. Their neutral mineral tones add contrast and texture in freshwater tanks and terrestrial enclosures while remaining chemically stable when properly rinsed before use.
Advantages
Polished surface finish reduces sharp edges and potential harm to fish and small invertebrates while preserving a natural stone appearance. The medium grain size (30–50 mm) is versatile for both small- and medium-scale layouts, enabling placement as single focal stones or as grouped elements. Supplied in a 5 kg bag, the stones offer convenient coverage for partial landscaping, trimming or adding accents without excess material. Being natural mineral stones, they are durable, inert under normal aquarium and terrarium conditions, and require minimal maintenance once positioned.
Suitable for
Freshwater aquariums as decorative hardscape and substrate accent
Terrariums and paludariums for ground cover and structural elements
Plant stabilisation and anchoring of moss or small epiphytes
Creating hiding spots, visual contrast and layered landscapes
Key specifications
Stone type: natural polished decorative stones
Grain size: 30–50 mm
Finish: polished, smooth edges
Package weight: 5 kg per bag
Colour tones: neutral mineral shades suitable for natural layouts
How to use
Before placing the stones in an aquarium or terrarium, rinse them thoroughly under running water to remove dust and surface residues; do not use soap or detergents. For aquaria, perform a soak and final rinse to ensure clarity of the water after placement. Position larger stones first to establish the basic layout, then add mid-size and smaller pieces to create depth and natural transitions. When used with live plants, press stones gently into the substrate to stabilise roots and prevent uprooting. Avoid using the stones with delicate saltwater invertebrates unless compatibility has been confirmed for specific species.
Usage recommendations
For best visual results combine several stones of different sizes from the bag to create layered arrangements and natural-looking focal points. Regularly inspect for accumulated detritus and clean individually when necessary to maintain water quality and terrarium hygiene.
