So it came down to this, I am getting critters tomorrow and that crab had to go. I gave it fair enough waring, but its not my fault that it cant comprehend what I am saying. I may have done this the unorthodox way, but a means to and end for sure.
I was sitting next to the tank, on the side that he hangs out on. Turned on my new 5 LED flashlight I got just to look at the tank at night and shined it on the rock. Something scurried into the rock that caught my eye. "that little f&*^er made it past the skewer. Not tonight he wont!" I started taking the canopy off, the glass cover off, and cleared room on the table. (avert your eyes if you dont want to read the rest, but yea he is dead) I went into the kitchen to get the skewer, and a towel. Moved the chairs close to the tank and stood up on them. I then reached into the tank, and pulled out the 15 pound rock and quickly went over to the table. I set the rock down on the table and lifted it up on its side. I shined the light into the hole he was hiding in and didnt see him, figures right? I then set the rock down and quickly scanned the tank. I didnt see anything moving so I figured he had to be way up the hole in the rock. I stuck in the skewer and started jabbing and poking and pushing and pulling and everything else. Nothing. I set the rock down and sat back in the chair dejected. I had a choice to make, leave the rock out and wait for him to come off if or put the rock back and try again later. Just then I had imagined the peppermint shrimp i am planning on getting being eaten by this little crab. No way that is happening. Again I tilt the rock up and start jabbing away in the hole. I must have jabbed a little too hard as I broke off a piece of the rock. At that moment the little crab fell out of the rock and startled me a little bit. I dropped the rock and it fell to the table, only about an inch. Needless to say, luck was not on his side as the exact place he was, was right where the rock made contact with the table and he got squished. I didnt realize it as I picked the rock up and started looking for him. Not finding him I flipped the rock over and saw the squishyness. I had a mini celebration and then quickly cleaned him off the rock. I then placed the rock back into the tank and situated it to make sure it wouldnt fall. I tried to get a better look at him and sure enough, the claw tips were black. "Hasta la vista, baby"
The rock has been back in the tank for a while and everything that is noticeable with life, the dusters and coral, are all acting like normal. I am sure there will be a few casualties of being out of the water for a total of 3 minutes, but I am relieved that the crab is gone. I will be checking the water tomorrow morning and as long as the ammonia is 0, its off to the LFS to get the critters.
