These guys come from temperate waters and do much better at lower tank temperatures. Most people would require a chiller. In fact, Steve doesn't even keep his in his reef tank....it's in his coldwater reef.
I had one for about 6 months named George. No one liked the price so I finally just dropped the price by a lot and he was gone the next week. I handfed him. He also liked to be pet like a dog. I would pet him for a while, then he would tilt so I could get his other side. I truly hated to see him go but when payroll is coming up and you're short on cash you have to make a business decision sometimes.
In the states, they are a very expensive fish. Only the males are attractive like that....the females are quite ugly IMO.
