I've had my tang for about a month and a half now and he's still very shy. Hides a lot, and will hide as soon as there is any sudden movements or if I even walk slowly over to the tank. I put the norI on a paper clip and tied some rope to it and lowered it down and left it there for quite a while. he ran away from it, hid for a little bit, came out and has been swimming around since but hasn't showed any interest in it what so ever. What can I do to get him to start eating it?
