My sea tank. Do you have any opinions?😊

I have two mangroves in my marine tank. The taller one worries me a lot. Its top mature leaves stretch far outwards, and the new young leaf at the apex hangs down limply.

Some leaves were submerged under water before, and I only use yellow light during the day with blue night light. I also took it out many times recently, making its stem slightly soft on the surface.

Does anyone know what’s causing this drooping? How can I fix it?

I maintain a small mangrove island aquarium, restoring coastal wetland ecology in glass tank. Looking for aquascaping friends to share daily updates!😃

Current tank update. The anemone is fully expanded, and all fish settle in well. Pretty satisfied with the current system.
