urchin compatibility

i was just wondering if its possible to keep different species of sea urchins in one tank.

Yup, they dont attack each other so its fine. I had a pincushion urchin, pencil urchin, and a rainbow urchin all together in a 50g glass tank, and about a month later I noticed that the pincushion spawned in my tank.
