Ten days ago I got a blue tuxedo urchin at my LFS. It's been happily munching on coraline algae and roaming my tank under a pile of shells and other small pieces of hard scape since it was acclimated to the tank. This morning, when I walked past the tank, I noticed that it now has a green discoloration at its widest point of one of the blue stripes on its body and I'm not 100% sure, but it looks a bit like the tube feet in this region are less healthy than the rest. The pictures below are attempting to show this region but my camera is having trouble focusing close up due to refraction issues (it kindly obliged for the picture by staying on this side for me 🙂 ). I'm unsure as to whether this spot was there when I bought it or not since it has kept itself pretty well completely covered in shells since before it was bagged for me and stayed that way until this morning. It's still moving around this morning with similar behavior to the last ten days, just lighter shell cover. You can see it's still wearing a number of shells. Any thoughts? I can't imagine how it might have injured itself overnight, so I'm guessing it is an infection of some kind. I'm not aware of any treatments for sensitive inverts like this for infections, but open to suggestions. Mostly just interested if others have had experience with this.
I'm recruiting a cleanup crew for a 16G and I've read this ode to the Tuxedo Urchin. They are "guaranteed to vigorously graze a wide assortment of algae". My idea for the 16G clean up crew is: For algae: 1 Tuxedo Urchin For uneaten food: 1 or 2 nassarius snails, 1 or 2 astrea snails. (Do I need more?) Would one tuxedo urchin do well in a 16G, keeping algae under control? I assume more than one would starve in a 16G.
