Yeah, I really wouldn't think a cleaner would be either. They spend so much time in the "customer service" business, it's hard to believe he might have had a bad day and whooped some wrasse--get it? wrASSe=-)
I had 2 idols and failed with both in less than 6 weeks. Both were from the Maldives if memory serves me. I got them to eat a little, but they succumbed to ich each time in QT....bad response to copper, putting the nail in the coffin.
I gave up. Year later, a Moorish Idol from Hawaii came around size small. It was a little more in price believe it or not. I think I paid $70 plus shipping. Got him and he was about 3 inches. Lots of energy, ate mysis and pellet the first day. Very bold fish. 4 weeks in QT then into the display without issue. He eats just about everything.....flakes not so much. The only thing I have done with him that I wouldn't have if not read to do was to feed him 3-4 times a day. I think they have a very high metabolism and need to be constantly gut loaded. I believe it is transit times without food that causes an irreversible slide down hill. In this case, he was from Hawaii and I think that may have helped reduce stress and malnourisment. I don't see Hawaiian MI's come up anymore. Maybe it's just me. They are really common out there too.
