1.A normal Rose foot.
They will be solid, no rips or damage to it when healthy.
Picture taken of a rose on the glass showing the bottom of it's healthy foot.
There are times when the foot may be damaged, as in ripped and usually they will heal over time.
Their foot is almost always buried deep in the rock work of your tank so it is not usually seen.
They do not plant their foot in sand like other Anemone's do, they need rock work to hide their foot.
If your rock work should fall and the Anemone's foot is in it figure there has been damage.
When moving any rock work in your tank make sure you do not move the rock that his foot is attached to.
They rip very easily so be careful when moving things around in your tank.
2. The normal Foot
Here are some pictures of some of my Anemone's with their
foot deep in the rock work.
They will not put their foot down in sand like other Anemone's
and attach to the bottom of your tank, rather
they will send it deep in between rocks and stay there.
If you look at many of the other sections on my site you will see
a lot of Anemone's with their foot buried deep in the rocks, this is just one example.

2. The foot in the Rock
And a newer picture of several Anemone's feet in the rock.
In the picture below, there are three Anemones with their foot planted and attached to the rock work.

I never recommend removing an Anemone from glass unless it is attached close to an intake
filter.
If you do need to move it you will need to first use your fingernail, if you don't have them, get a credit card.
Slowly push the tip of the card under a small section of the Anemone's foot.
Slowly move the card around the outer edge of the foot, it will release as you go.
Now move the card slowly towards the middle of the foot, gently pulling upwards away from
the glass as you move the card .
Your Anemone should now release it's foot and can be gently placed in another location in your tank.
