tuxedo urchin spawned

[makana]

My urchin spawned the other day when I turned the pumps back on after feeding. I thought something was wrong with him at first. Clouded up the whole tank. I was a little worried about it polluting the tank but didn't really notice any effects when I tested the next day. Did a good size water change anyway. Makes me wonder how many times he spawns that I don't see it. I would have to think it adds a pretty good bioload to a 29g system.
