Fish Crazy
well i have a white ring urchin. it was at the top of the tank and as i walked by i got an idea. i took a piece of dried algae and i put it on it's spike on the top of it to see if it would take it. well to my suprise it did. it pinched it between two of it's spikes and it transported the algae from the top of it's "back" to the botton near it's mouth. thought it was really neat, and thought i'd share with everyone.
