Description

Ornament Rock Formation Medium 20×8.5×16.5cm — Slim artificial rock formation rated for coldwater, tropical and marine aquariums

Natural stone is heavy and some types change water hardness, so an artificial formation is a simpler way to add height and structure to a tank. Ornament Rock Formation Medium 20×8.5×16.5cm (SKU: 36744) is an Aqua One artificial rock ornament from the maker’s Natural range, 20 cm long, 8.5 cm deep and 16.5 cm high. Its slim depth lets it stand close to the back glass or a background without taking much floor space, while the height lifts the line of the aquascape behind plants and smaller ornaments. Aqua One rates it for coldwater, tropical and marine aquariums, so the same piece works in a goldfish tank, a planted community or a fish-only saltwater set-up.

Aqua One describes the Rock Formation as easy to set up and a way to add life and colour to an aquarium, and it sits within a large range of rock-style ornaments that can be combined for a bigger hardscape: the Rock Cobble pieces (37425 to 37427), the Rock Formation Slate in 40 cm and 45 cm lengths (37514, 37515) and the Round Cave Diabase hides (37516 to 37519). A single formation suits a 45 to 60 cm tank as a background feature; in a larger tank two or three placed at different depths read as an outcrop. It sits directly on the substrate, and bedding the base a centimetre into the gravel or sand stops it rocking. Gaps between the formation and other decor become hiding spots for small fish and shrimp. Rinse it in warm water before use and clean it at water changes with a soft brush, without soap or chemical cleaners; in a marine tank the same routine keeps film algae down.

Usage & Application

When to Use

• Background height: A 16.5 cm vertical element behind plants and ornaments.
• Narrow tanks: Only 8.5 cm deep, leaving the floor free for swimming.
• Marine fish-only systems: Rated by Aqua One for saltwater as well as fresh.
• Coldwater and tropical: Equally at home in goldfish and community tanks.

Placement & Care Guide

• Rinse first: Warm water only; no soap or detergent.
• Bed the base: Settle it into the substrate so it does not rock.
• Group in odd numbers: Combine with other rock ornaments at different depths.
• Brush clean: Soft brush at water changes; no chemicals.
