I got 2 emerald crabs as I have some in very hard to reach places. I just took those readily accessible with dental pick and tweezers.
The problem with the Emerald started once the bubble algae got undercontroll. One started eating my Zoas (always seemed to go for the more expensive/desirable zoas) so off he went.
Couple days ago, I noticed the other one was picking on my mini colony of Maleficent SPS. At first, I thought he was picking off algae but I watched it for awhile and he literally took a chunk of the SPS. Good things I caught it right away and will be rehomed to my buddy's Mangroves tank.
He is a big one as well.
