The anemone is attached to the bucket. It is a like green colorNearly impossible to say from that pic. try to get some new pics once it is in a tank and we can see tentacles, mouth, etc. is it attached to the bucket? Are the tentacles sticky? beyond these things better pictures will definitely help.
I will say that the color from these pics make it look like it may be pretty bleached, but hard to say.
It's a sign of unhappy...for easy language nematocysts is the anenome sticky stuff that they use to catch food. Not all anenome need to catch food and most of the time light and clowns do the work without us. But when we do feed them they use that sticky stuff. So if it's gone it's a sign of unhappy or going unhealthy.Is it a bad sign if they're not?
