The longspine urchin was the first saltwater invert that I really fell in love with. I currently don't have a tank suitable for one but I have a question to the people that keep them. So because they get really big and can sting you, if you had to remove them, how exactly are you going to get them out of the tank? Seems like it would be a massive pain to do so, if not nearly impossible if they're jammed in between the rockwork.
