Well, we obtained one of these fish about 5 months ago. Didn't know anything about them. This is our first saltwater tank(75g), and we are mostly passive fish, lots of crabs/shrimp, live rock, and a couple corals. The fish store sold him to us with little information about him/her, but we took him home anyhow. He is still alive to this day and seems very healthy. We feed a large variety of foods (only feed once a day) of krill, lobster, brine, bloodworms, veggie flakes, and algae sheets. Our mushroom coral has been suffering since, but is still alive. Only just started researching these guys and realizing how hard they are to keep. I don't know, maybe we got lucky, but i must say they are cool looking fish and remains as one of my favorites in the tank. They can survive well in a house tank.
