T-Rex Tree Trunk Tropics Aquarium Background/Filter - 10 Gallon

Tree Trunk Tropics brings the feel of a river's edge, bordered by trees and overhanging roots, into a 10-gallon aquarium. Use it purely as decoration, or connect it to an air pump (sold separately) to turn it into an efficient biological filter supporting up to 1 inch of small-to-medium fish per gallon with regular water changes.

Pre-fitted with two lift tubes and air diffusers, it's ready to plant with live aquatic plants or dress with artificial décor. Ideal for small fish under 4 inches, frogs, tadpoles, newts and freshwater shrimp.

• Dual-purpose background and biological filter
• Pre-fitted with two lift tubes and air diffusers
• Works with or without an air pump
• Fits standard 10-gallon aquariums (20"L x 4"D x 11"H)
