What does this mean on an anemone

[Reef_Geek]

sorry to hear.

sounds like it's a new tank... so a newly added anemone?

From selling these things over the years... very important to avoid damaging the foot on anemones when selling them. Best practice for a sales tank is to bury a layer of window screening about 2 inches below the surface. Anemones can be gently peeled off the window screen for sale. I personally cringe when I see anemones being worked on, to come off rock/glass for sale.
