One of the main reasons people love aquarium plants so much is their power to absorb toxic nitrogenous compounds produced by fish waste. But what if your fishes are natural plant killers? Well, if they are, don’t worry! We have got your back. It’s time for you to get a pothos plant for the aquarium! Well, pothos in the fish tanks won’t filter out toxic particles from the aquarium. Still, they can reduce nitrate levels and algae growth to a great extent so that you don’t need to change the water regularly to keep your fish healthy and happy.
