The scribbled is a voracious caulerpa eater, but may nip green colored corals before learning they're not a food source. Mine nipped two tentacles off my frogspawn.
They are spooky and seriously venomous like all rabbits, and if you are working in your tank moving rock, be advised they go rock-camo and lean against the rocks for protection in the shadows. Use long gloves over leather gloves while moving rock in a tank that contains a rabbit. Their sting can cause local tissue necrosis [blackening and death of tissue], a lot like a fiddleback spider bite.
