Urchin not moving

[pseudorand]

You can't see him well in the picture below but the thing that piece of shell is hanging on to is a tuxedo urchin. He's been there for at least a day without moving. I've had him for over 6 months and is always moved much more than that. Should I be worried?

Yup, mine will do the same thing. Sit in one spot for days.

As long as it doesn't shed it's spines, it's still alive.

Perfectly normal mine will stop and munch for hours on the right spot. He/she probably found a good spot for food and is just cleaning. Or like other post just taking a nap.
