So I got a new Halloween urchin and he's getting settled into my tank. I thought he'd be OK, as I have a LOT of coralline algae in my tank. But I read that they need seaweed, in case there isn't enough algae in the tank. So I attached a sheet of dried seaweed and was pleased when the urchin headed to it...
But he doesn't seem to be eating it -- he's got it wrapped over his top, I guess as camouflage. So, do these urchins need seaweed to eat? I don't really want to add it for him to wear -- the effect's quite unattractive...
