Create a dramatic, natural focal point in your aquarium with this Tree Root Dome – a stacked root–style hide full of arches, tunnels, and shaded retreats. Fish and shrimp can dart through the openings, rest in the interior pockets, and explore the layered surfaces while you get a centerpiece that looks like it was pulled straight from a wild riverbed.
This piece is 3D printed in a single solid color using PLA or PETG, depending on the filament color you choose. The photos show how it can look when fully painted; your item will arrive unpainted, with all of the rocky root texture baked into the model so you can enjoy it as-is or customize it with your own paints.

5 Steps to Introduce into a Fish Tank
How to Safely Add This PETG Decoration to Your Aquarium:
Inspect the Item:
Ensure there are no loose strings or sharp edges. Sand lightly if needed.
Rinse Thoroughly:
Rinse the decoration under warm water (no soap or chemicals) to remove any dust or residue.
Optional: Soak in Tank Water:
Let it soak in a container of aquarium water for 24–48 hours. This helps to equalize temperature and water chemistry.
Check Fit and Placement:
Gently place it in your tank. Avoid pinching live plants or trapping fish.
Observe Fish Behavior:
Monitor your pets to ensure they interact well with the new decor. Most will begin using it as a hideout shortly.
