Gurglebuster was getting a bit loud so I pulled it out to adjust it and found these two in there. I've seen a few of the larger and lighter of the two (about the size of a nickle) in the tank and they dont seem to be bugging anything. I believe it is a portunidae but that is the first of the darker crab I've seen and have no clue what it is.
