T-Rex Aquarium Decor – Tree Trunk Tropics Background
Tree Trunk Tropics provides instant landscaping for your aquarium. It functions as both a background and a biological filter, offering a framework for adding landscape elements such as wood and aquarium plants.
Once installed, it gives your aquarium an immediate environmental feel, simulating a river’s edge bordered with trees and overhanging roots. You can add T-Rex Aquavine, Aqua Root, plants, or other aquarium décor.
Live aquatic plants can be anchored in the foam by making a small slit and inserting the roots. Artificial plants can also be inserted directly into the foam.

The tree trunk background adds a natural look to my 20-gallon tank. I used it with live plants and it holds them well. The roots and overhanging parts look realistic and the fish seem more active now.
Stephen Johnston –
Great for creating a tropical river edge effect. I added some artificial plants and it looks very natural. My shrimp are thriving and the water clarity has improved.

Easy to install and fits perfectly in my aquarium. The foam is stable and holds the plants without collapsing. I love the way it enhances the overall environment.
Trevor Gray –
It works well as a background, but the foam can be a bit soft. I had to secure some plants with extra glue. Still, it’s a good base for a planted setup.
