I have taken different live plants and attached it to the tubes with monofilament fishing line and it works great for me . Same idea as attaching moss or other plants to rocks in the aquarium . just a idea for you to try, like I said it works for meI use wood and fake plants along with a black background

Cannot do that tank already filled with water and running>Put your input and output hoses through the tank bottom if you want a clean look. Particularly useful if you have a tank viewable from all sides or circular.
You will need double taps on the canister (obviously).
