I got a Radiant Wrasse today. I'm a bit concerned that he has been hiding since I put him in the tank. In fact, I have no idea where he is. I'm assuming under the sand, but your guess is as good as mine.

Is it normal for a wrasse to hide for a while after being added to a tank? The last wrasse I had was a six line wrasse. He never hid. I don't have the six line wrasse anymore.
