I dont know why no one has asked but for those that dont know, urchins grab stuff and tote it around with them, pieces of rock, loose corals, equipment. if its not nailed down they will lug it off, and if they can pry it loose its not nailed down.
Yea I had one for a little while in the beginning and I got rid of it because of that reason. It literally rearranged my tank, that would of been ok for a large tank but in a 29gal cube it was pain.
