Catalaphylia closed and white thing on tentacles - Need help

[andyinfo]

Hi everyone,

Since yesterday, my Catalaphylia has been closed and hasn't opened much. My NO3 is close to 0, and my PO4 is also very low. Today, I noticed a white thing on the tentacles of my Catalaphylia (see the attached photos).

Does anyone know what this could be? Should I be worried or take any specific actions? Thanks in advance for your help!

My Catalaphylia has opened up now, but it still doesn't look very healthy. There's still a white thing on a few of its tentacles. I'm not sure if this is something I should be concerned about. Any advice would be greatly appreciated!

Looks like they could be mesenterial filaments. If that’s the case, it could mean it’s trying to fight something, or it may be hungry.

I would try to feed it.
