Deflating roses and why do they do it?

Roses deflate to get rid of waste, that is to say, poo and expel water.
They will expel at least every 2
days,sometimes daily.
It is a process that is done by shrinking up so
much that you think they are dying but are not.
They need to expel
their waste and replace their body and Tentacles with fresh water
regularly
and here is what they look like when doing so:
(picture below is an old one, newer ones are after it)
Look closely, you can see the brown stingy junk coming out of it's mouth (below) that is the poo
Below, new pictures
Here is a great example of an Anemone that has deflated, a before and after shot.
This Anemone is my largest in the 125 gallon and each month she lets go up to 3 bud babies.
Here she is., enjoying the day.

And a few minutes later, having to expel waste and water.
Hard to believe it is the same Anemone isn't it!
She does this daily and is about 12 inches across when fully open.
"As seen by the clown in the above picture, who is 2 inches long.
All of the Roses in the picture above are buds from her.
(there are 5 just in this picture alone)
She has budded more then 20 so far.
"The majestic one".
(I call her that just because she is so awesome)"

Thought I would show a picture of her mouth once she started to inflated again
It was wide open, ragged and just plain scary while deflated.
I usually panic a bit when they hang, as in the picture above and watch for them to regain their beauty.

Another Anemone doing it's daily thing.
The light brown in the center of the white puffy mouth is
the Poo.

Here is one that is expelling the scales along with the rest
of the waste left over from the Silverside that it ate.

Mushroom Poop you say?
I new you were asking just that question, wondering what mushroom poop looks like.
Well, wonder no more.
I have solved it for you.
Below is a picture I took of one of my fuzzy shrooms pooping.
It looks identical to Anemone Poop when it comes out. I thought it was a great picture
so decided to post it also.
As it all looks the same when coming out usually. (color wise that is) and stringy.
Just after this large piece was let go in the current. My hermits had a hold of it and were having
a big dinner (yuck).
Here is an old picture taken in 2006
of my newly acquired bleached BTA pooping.
It has two mouths and poops out of both.
(see section on two mouth)
