Anemone not looking good but doing good?

One of my gbtanemones has looked like this (see pic of the nem) for about a month maybe more it eats and poops normally doesn't move from its spot I'm not sure if this is normal or should i be concerned and remove it ?
 
If you said it started today, it looks like it ate a lot or it was splitting.
But.....
Since you said it has been like that for a month.... I don't know...
