🪸Coral Chamber🪸

Part cave, part coral palace, and 100% prime underwater real estate! 🐠

The Coral Chamber transforms your aquarium substrate into a spacious underground hideaway. Designed to sit against the aquarium glass, two natural-looking surface entrances lead into a wide chamber filled with sculpted coral-like pillars.

The irregular pillars create multiple passages, sheltered nooks, and areas for appropriately sized aquarium residents to explore. Meanwhile, the open viewing side lets you watch everything happening inside through the glass—it’s like having your own private window into a hidden coral kingdom! 🫧

Once surrounded and covered with substrate, only the two surface entrances remain visible. The chamber below disappears beneath the sand or gravel, creating a surprising underground world that blends beautifully 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 chamber with substrate, allowing both surface entrances to remain visible and unobstructed.

Avoid packing substrate into the entrances or between the interior pillars. Choose a size whose smallest entrance and interior passage 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 Coral Chamber 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.
