There is a display of Bengaii Cardinal Fish with Hatpin urchins at the Vancouver Aquarium. The young Cardinals are supposed to hide in the urchin spines, but I saw no evidence of that in the display.
The babies do hide in the spines of the Diadema urchins. They don't do it for very long though, just while they're really small.
