I was attacked once by a blue triggerfish in Safaga. It was completely my fault, though, as I followed it towards its nest on the sand. It bit my fin several times. When I encounter blue triggerfish now, I am a bit more cautious. This one was having his breakfast during a very early morning dive and swam towards me. I took a few pictures without disturbing it!
