Undergravel Fish Tunnel

Undergravel Fish Tunnel – The invisible cave for your fish

The Undergravel Fish Tunnel is an innovative aquarium decoration that creates a safe and attractive hiding place for your aquarium inhabitants without disturbing the overall appearance.

Key features:

• Underground placement: The tunnel is placed under the substrate (gravel or sand). Only the entrance opening remains visible, creating a natural-looking cave.
• Safe retreat: Provides shy fish, bottom dwellers (such as catfish or loaches) and young fish with a stress-free place to rest, hide and spawn.
• Close-up observation: Thanks to its special design, the tunnel can be partially positioned at the front of the aquarium glass. This allows for unique and exciting observation of the fish in their shelter.
• High-quality material: Made from 100% natural ceramic, the tunnel is free of harmful substances and completely safe for fish and the entire aquarium ecosystem.
• Biological benefits: The porous ceramic surface is ideal for the colonisation of beneficial filter bacteria, thus supporting biological filtration and water quality stability.

Dimensions: approx. 177 mm x 196 mm x 102 mm

Application:

Position the tunnel in the desired location on the aquarium floor, ideally with the opening facing the viewer. Then cover it with substrate.

The Undergravel Fish Tunnel is the perfect solution for providing a functional hiding place that blends harmoniously into any aquarium.
