Ningaloo reef is off West Australia's remote northwest coast. It's the world's longest fringing coral reef, and this fellow lives there.
He's a Bluepatch Butterfly (Chaetodon plebius)
Shot with Canon 10D, Tamron 90mm macro in manual focus mode, 420EX speedlite using TTL, f/27, 1/180, using a fine quality West German-made housing.
Feedback/critique is most welcome.
Nice image! The only comment that I have is that you might try to brighten up the part of the fish that's in shadow.
But it's a nice photograph!

Nice shot. I like it as it is. If you try to lighten up the fish it will look un-natural. Right now it shows how he/she is peeking out from the coral. The coral casts the shadow on the fish and it works nicely cause it helps highlight the fish's face.
