The Mouth of the Anemone
The mouth of your Anemone should be closed most of the time.
It will sometimes swell to bubbles
when it is stressed or hungry or has just eaten.
I have some do
that when I do a water change also. It is nothing to be worried about
and
they will soon loose the swelling around their mouth.
But if you see any of the insides, go to the sick Anemone section.
Below is the typical Mouth of a Rose. It is always closed.
And a closer view of the same Mouth, above.
Another of the same Anemone.
When the above Anemone is hungry, this is what she does.
She also does this when she smells/tastes food in the water.

Below
Here is one all puckered up ready to try and swallow a Silverside.
It is too big, or so I thought but she got it down.
They will pucker up like this when hungry and or detect food in the water column.
The Anemone is the same one that is now in the 125 gallon tank with the True Perk clowns
hosting it.
She puckers like this every time I feed the tank.

Another perfect example of a swollen Mouth looking for food.
I have found that they can smell food in the water no matter what the food is.
When I feed Mysis shrimp this one immediately puckers its lips as seen below.
The picture above this sentence and below are the same anemone. Different feeding days.

Adding a few more pictures of puckered mouths looking for food.
Taken 2006 in my 125 gallon.
All of these are normal for an Anemone so there is nothing to worry about when you see it.

The picture below is just after I fed mysis to the fish and Coral Vibrance to the tank.
It wanted food and NOW so she got her Silverside.
The pretty baby below is in my 75 gallon. (16 total) She always bubbles her mouth when there is food


The end.
