Got these hanging off the live rock in my newly established 5 gallon nano. They seem to just float in the current, but also slide around and even seek out bits on other parts of the rocks! They even picked off a reef food pellet before it made it to the sand, but it was juggling it up and down, guess it was too much for it lol
 
It almost looks like a mini brittle star, @25 seconds it looks like the body drops down, but I haven't seen any that big before.
