Hello, so I've had these plants in this tank for a couple months now and I've recently just noticed that there are some browning spots on them that won't go away. I dose them with the recommended amount of Excel, Iron, Potassium supplements and there is decent medium strength LED
lighting. I looked like algae growth at first but I'm not completely sure what it is. I normally never had this problem until I stocked my tank with gourami's and angelfish. My shrimp are scared to come out during the day so they normally feed at night. Is it algae or is my anubias plants dying? Here are some pictures of my Anubias Plants. Do I need to cut these leaves off or is there a way to save them?
