Toadstool not looking good

[dueces]

I checked my water and everything is fine and nothing else in my tank is fine.
Any ideas?

sorry I meant everything else in my tank is doing fine. It is just my toadstool.

How long have you had it? How long has it looked like that? Sometimes they can "close up" for cpl days...I think they do this when they shed.

I had it for about a year and it has been like this for about 2 days. I guess it has done this in the past but it always freaks me out.

Any changes in water quality?

 

[dueces]

no I check out the water and it is fine....I might do a small water change to see if that helps!!

My guess is hes about to slime off. I wouldnt worry all that much yet though.

 

[unleashed]

hows your calcium and alk levels?have you checked those too?

From the vertical indention in the stalk and the shape of the cap (ie almost like two separate heads) I would consider bilateral fission (natural division) as a possible canidate.
It is over a year old and with good water and proper lighting this would not be abnormal. This can be a long process, cause stress (hence not opening) but not IME/O cause for worry.
It could just be in a mood also
Perhaps it is just the angle of the pic but my .02 anyway.

PS FWIW if it were about to shed it would not have polyps partially extended (unless it had already shed )
