Its got algae and the edges are slowly turning brown. Ive got it directly under a 26W CFL and it has a root tab right next to it, as well as having DIY CO2 and Flourish excel, so I am kinda figuring that its the pot...
As long as the rhizome is out of the substrate, you should be in the clear with anubias plants. I don't like to buy the types of anubias with that cotton stuff as a potting material. It's too hard to take out and I usually find it floating around the aquarium.
