Does anyone have this problem?

My blue legged crabs are eating all of my coraline alge up. How cane I stop this? Is there something else I can feed them to get em to quit?

Yea, It's the blue legs, I've been watching them and you would believe how much they will clear in a day. I have a 55 gal, 110lbs of rock that was covered in coraline along with this a cleanup crew for this size tank, so I have about 50 of them I would say. I don't believe I have an emrald. Do you have a pic of one?

Oh, ok I do have one of these, a real pretty green color, with a pretty good size body. When I got my rock I took one out that was about the size of a golf ball, I thought it was a bad crab.
By the way, thanks again for the site you emailed me, real helpful.
How big is your tank? Send some pic's if ya have any.

Buy a Flame Hawk fish and let him eat the blue hermits...or remove the blue hermits to a different tank.
I have never heard of hermits eating coraline algea...but who knows...
