🌊Tidal Junction🌊

Three entrances, one underground crossroads, and absolutely no traffic lights! 🐠

The Tidal Junction transforms your aquarium substrate into a branching tunnel network beneath the sand. Designed to sit against the aquarium glass, three naturally shaped surface entrances lead down into connected underground passages that meet within a roomy central area.

The three-way layout gives appropriately sized aquarium residents multiple routes for entering, exiting, exploring, and hiding. Meanwhile, the open viewing side lets you watch them navigate the tunnels through the glass—it’s your own private window into the aquarium’s underground transportation system! 🫧

Once surrounded and covered with substrate, only the three surface entrances remain visible. The connected tunnels disappear beneath the sand or gravel, creating a hidden network that blends naturally into your aquascape.

🌊 EASY TO ADD TO YOUR AQUASCAPE

Position the open viewing side flush against the inside of your aquarium glass. Surround and cover the tunnel network with substrate, allowing all three surface entrances to remain visible and unobstructed.

Avoid packing substrate into the entrances or interior passages. Choose a size whose smallest entrance and tunnel opening comfortably accommodate your aquarium residents.

Please rinse thoroughly with clean water before placing it in your aquarium. Avoid using soap or household cleaners.

This listing is for the Tidal Junction cave only. Aquarium, substrate, rocks, plants, and animals shown in the photos are not included.

Because every cave is 3D printed, subtle layer lines and small cosmetic variations are a natural part of the printing process and make each piece unique.
