I have 3 stalks of pulsing xenia (possibly the red sea kind). For the past few weeks I have noticed a split or kind of hole like thing starting on the stalks of all three. First I though it might be growing new arms, but as more time goes on it looks like the openings might be getting bigger. The hands look fine and the color hasn't changed. Is it slowly dying or doing something else? I know that I do have high nitrates that I have been working on getting rid of (I've been doing a water change once a week or every 4 or 5 days). I had a regular xenia decide it didn't want to live anymore and started shrinking away, while the rest of them look great. I think this xenia was what started the nitrates going up in the first place.
