Wow I never really thought of that. That's a great thought, I had them in there because I love the thought of a plant growing out over the top of the water. I will pull them out and see how everything looks after a few weeksVery nice!
Why the pothos? If Im not mistaken, pothos will take the food source for other plants. I had to remove mine because my ground plants started dying on me after about 6 months. They picked up about 3 weeks after I removed the pothos. Maybe it was just my setup but I think pothos are a bad combo with planted tanks.
