Black long spine urchin with predator fish

[Porcupine Reefer]

Hey so I thought about a long spine urchin for algae control in my tank, but I also have a porcupine puffer and snowflake eel. Can this urchin live with both of them or is his spines going to get chewed on.

In my experience you'll be fine with these.
