haha interesting story guys...I have a 55 gallon tank with ALOT of live rock and a powerhead right by one of the rocks...So one day im just watching the tank and I see the crab slowly coming up the rock nearest the powerhead. So then all of a sudden I dont know if it was an unexpected flow out or something, but the crab was cleaning the rock and then it just gets blown out of its shell
....The shell stay on the rock and the crab flew across the tank...It was killed instantly.
