There are various types of aquarium rocks available, each with unique properties and effects on the aquarium’s ecosystem.

• Lava Rock: Highly porous and lightweight, Lava Rock is excellent for beneficial bacteria growth. Its dark, rustic look is perfect for creating a natural backdrop.
• Ryuoh Stone: Similar to Seiryu Stone but with sharper edges and a slightly lighter colour, Ryuoh Stone is ideal for creating Iwagumi layouts.
• Petrified Wood: Offering a fossilized appearance, Petrified Wood is a solid stone that resembles wood, perfect for creating ancient, forest-like scenes.
• Manten Stone: A premium aquascaping rock, Manten Stone is known for its complex detail and varied colouration, ranging from light grey to reddish hues.
• Mountain Stone: As the name suggests, this stone is ideal for creating mountainous landscapes, with its rugged surface and varying sizes.

Benefits of Aquarium Rocks

Apart from enhancing the visual aspect of aquariums, rocks contribute significantly to water quality. They provide shelter and breeding grounds for fish, creating a more natural and comfortable habitat.
