I have a arrow crab about 5 inches with legs, that i got about 2 months ago, and has grown like a weed. He is suspect in a number of missing inhabitants... :evil: Animals missing-6 Green Chromis, Clown Goby, Blue Leg Hermit Pieces laying around, and a large sally lightfoot crab. A few days ago, we caught him munching on a blue legs legs... Then, later in the week, saw it eating one of our brand new green chromis, and was gone in less than 10 hrs. All fish in tank, now stay away, because when they get close, he stabs at them with those long, pointed legs and his conehead top. Should i put him in the sump with the other evil doers? Or does anyone want an evil, fish shredin crab?
