Hanging Plant holder on aquarium

I had many overgrown devil's ivy and I don't want to just throw away,  and an aquarium with some over-nutrition issue.  So I came up with this. 

This compact holder is designed for holding plants on aquariums, allowing roots to grow downward and absorb nutrients from the water, and also creates a plant wall on a side of the aquarium.  Compatible with Aqua One Horizon aquariums, or other fish tanks with glass thickness of approximately 5-6mm."
