Cool unique fish – love watching it stalk and hide in plain site
however, beware, added a pair of fairly sized CB yellow lined gobies that I thought would make it.
I was wrong – both gone in two days – so keep it in tanks with larger inhabitants

Really cool fish. I’d describe its movement as slithering more then swimming. Just slowly patrols bottom of tank pecking at things. I haven’t really seen it eat anything other then some frozen shrimp, I assume it is hunting pods. It lives in a hole in the center of a colony and always pokes its head out right above the polyps.
