We added a Brittle Star about four months ago. For the first few weeks, it made a home in a specific section of rock and pretty much hid all day. At night, we could see one or more legs sticking out, moving around, etc. At about the 4 week mark, it disappeared. We thought it headed deeper into the rocks.
At about 6 weeks, while cleaning the sump, I noticed the Brittle Star was in the sump. This guy traveled through 20 feet of 1" diameter pipe, and 2 ball valves. He dropped into a large filter sock, had to climb out of that sock, then wandered across the skimmer area, climbed a glass partition, and made a home in a rock pile.
Every now and then, I toss in a few algae wafers. The Star never fails to appear, snatch a wafer, then head beneath the rock pile. Lately, this guy has developed a new habit of climbing into the Skimmer area, crawling along the heaters, then returning to the rock pile.
Here's a video (not awesome quality) of his return trip to the rock pile:
