APorter & Art: Thank you both very much.
Bax: Thank you, also. The only other fish in my tank that might possibly go after them is the Sixline Wrasse but I don't believe this has been documented. Not to mention, he's a bit too large to get into the branches of SPS. The Pipefish definitely are "designed" for this. I currently have four in there and may add a few more.
Lunchbucket: Thanks for the kind words. As to your request for updates... I forgot to mention that one of my water-change tanks (Rubbermaid trash can) sprung a leak so I had to replace them. I did both because I went with a stronger 50-gallon gray Rubbermaid in the square shape with integrated hinged lids. Going this route has allowed me to increase my water-change capacity while still using the same footprint.
Marc: That full tank shot is three photos (left, center and right) stitched together in Photoshop. I've learned that moving the camera as far from the tank as possible and placed in the exact center on a tripod produces the best results. Alignment of the photos is closer at their edges so the software has to work less and the end result is almost completely undetectable.
I took that shot with the closed loops off for about an hour which helps to eliminate waterborne debris. In addition, I do run ozone which greatly adds to water clarification. That and a big 'ol skimmer, carbon, a filter sock and a canister filter.
Thanks for all the kind words and as per your request, here's some recent photos for your perusal. First up, a shot of one of the Pipefish I managed to take today.
