here is a picture of my emerald crab finaly caught in the act...i'm going to bring him back today if i can catch him......
he is tugging at and eating my tube anenome......i'll post later to say if it opens back up again, its just all kinda hanging out righ tnow.......
I've seen that happened before. Remember, the tube anemone's outer body are detritus. If there is nothing for the crab to eat, he'll find whatever he can get a hold of. The tube anemone will just rebuild it's home eventually.
