I have a pretty fully stocked 240 g tank. My main goal is to buy enough of the right plants to do a good job of reducing nitrates. I have an aro, 2 peacock bass, an African Tiger Scat and 5 bichirs. Can you recommend some plants for my tank that the scat won't eat and that will do a good job of reducing nitrates? I just have a small 4 ft light fixture for now with a regular bulb I bought from Home Depot.
