Surprising bedfellas

Last week I was checking out my tank a couple hours after the lights were out. I had a big scare as I thought I had a couple dead fish. My mandarin was on the sand bed halfway under a rock. Right next to him - they were touching was my orange back wrasse. I thought they were dead - and that I hadn't paid attention when I was feeding that evening.

On closer inspection, I found that they were alive. Yeah!!!! Previously I had noticed the wrasse at night in the upper left hand corner of the tank. What was so amazing to me, it that I swear they were touching!
