Mine never bothered a thing, it was a really cool critter. I had a ton of coraline alage, I couldn't even see thru the side glass anymore and I got it to trim it down a bit.
It cleaned the side glass to almost clear and cleaned up the back glass...there was no algae to be had. Sadly after the year, it began to loose spikes, a sign of starvation. I had to find him a new home. He looked like a black pincushion urchin by the time I got him out of the tank.
One lesson learned....acclimate it in a glass container. I used the styrofoam container and it dug in so tight I needed to use a knife to get it out of there and let the segment float until the thing released it...I had broken spikes everywhere. It recovered well and I had it a little over a year before it had to be removed because of starvation.
It can aim it's spikes, and it can get in tiny spaces, I don't know how. But when it traveled, the spikes looked like they moved in and out like a star burst...really awesome....LOL....I also learned that little red spot is not an eye, but it's rectum.
