So I've got a sea urchin and I've had him for a very very long time and he has grown so much. Well anyways, I was doing some rock rescaping, I only moved two rocks around to create more caves. I had to pick him up and move him out of the way so I didn't hurt him. I know I'm not supposed to really handle them too much and I never do, until when I had to move him. When I went to pick him up the very very hands of his spines were very very fragile and broke off. the whole spines never broke but just the very very tips. Would the be expected maybe because it's new growth, and weak. The rest of his spines seemed okay and strong.
