I wish I could. This tank has an ultra tight fitting screen top due to the 8 wrasses that live in the tank. Not to mention the three suicidal zebra bar gobies (they think they can fly). I'm about to the point of gluing the thing to the glass somewhere. I own at least 6 algae clips, I can only find one right now (and the urchin has it).

As much as I fuss about the thievery, the urchins provide me with endless amusement. Their wardrobe changes daily, some are pretty high class, others, not so much. But I do adore them. Otherwise, why would I own 5 of the little thieves?
