Hello! My weeping willow toadstool has been super happy and healthy for a couple months now but all of a sudden it starting acting weird. Its polyps won’t come out and it’s making a concave cone shape. The nitrates (16.5) and phosphates (.02) aren’t terrible so I’m not sure what’s wrong with it. I was planning on an 10 gallon water change tomorrow to bring the nitrates back down but the toadstool should react that way to elevated nitrates, right?
Any thoughts?
