Xenia closes randomly

[homebrewdude]

I have 3 patches of xenia in my tank. It seems that they randomly close tight. For no apparent reason.
The majority of the time they are open and pulsing.

Anything I should worry about?

I think that means that head is eating something... not positive on that tho...

Random closing and re-opening is nothing to worry about. In the pic you posted, it's possible that snail brushed up against it and caused it to close.

Our tank inhabitants have caused our Xenia to close just by getting close to it -- direct contact not even required.

I am going to agree with fsn77. When anything gets close to my xenia it closes up like that. Then it reopens again in about 15-30 minutes.

I agree with the previous 2 postings. Mine close up as well when something bothers them.
