yes he is a very strange fish, the first few days he hide, then was out for maybe a week, then he hide in a cave for the next 5 months, I would see him moving from one cave to another and sometimes he would lay on the rock at the mouth of the cave, then he decided to come out, I thought he was dead as he was out and in the sand bed just laying there, he then moved into the clowns area and sat watching them, they went mad, covering him in sand, they accepted him after a day, he stayed with them for a week, and now for the last 2 weeks has been in the middle of the tank in the sand bed digging! Just wish he would eat more.
