Build an open, dramatic aquascape with the Real Reef Medium Arches four-pack in the bold Midnight Black finish. Each box includes four handcrafted arches designed to create instant caves, bridges, swim-throughs and elevated coral-placement areas.

The dark finish provides a sleek, high-contrast foundation that helps brightly colored fish and corals stand out under reef lighting. The open arch design promotes water movement throughout the aquascape while creating shelter and defined swimming paths for aquarium inhabitants.

Aquascaping Possibilities

Use the four arches individually to create separate islands and territories or combine them into a larger interconnected structure. They can be stacked, bridged or secured with reef-safe glue, epoxy or aquarium mortar to create custom negative-space aquascapes.

The curved surfaces provide multiple coral placement areas while the openings underneath create natural shelter for tangs, wrasses, blennies and other marine fish.

Preparation and Cycling

Rinse each arch thoroughly with RO/DI water before placing it in the aquarium to remove dust created during packaging and transportation. This rock arrives biologically sterile and must be properly cycled or seeded with beneficial bacteria before livestock is introduced.
