Parrot fish are hard to photograph. They see me coming and head away. But at night, I have been told they sleep. Fish sleep? Eyes open? But they weave a membrane around themselves under the coral. A bubble – I was told. Well it seems that there is a membrane. It’s incomplete. What I understand is that is you touch the membrane the fish will move. I decided to let sleeping fish lie. He did not respond to the flash of light. Both of us were happy.
