Glad to find this thread still going, though I had to look for it for awhile
So we brought home a long spined urchin a few days ago. Was hoping it would munch on some of the getting-to-be-nuisance macroalgae, but so far the urchin has only eaten coralline and rock
We've been playing "find the urchin" during the day with the monster Christmas gift flashlight. Heck, we play "find the urchin" at night with the flashlight, too
Yesterday, the urchin was roaming around way after the halides went on and I got some footage of it....

Last night, it was on the front glass, so out came the camera again....
