A flat, well-camouflaged animal such as an anglerfish really benefits from a low angle of view.

                            Looking down can work in situations where there is enough contrast, e.g. subjects at or very near the surface, also if you are using filters instead of flash.

                          Look for subjects in good situations, and good viewpoints.

                        Some fishes naturally hang around in groups together, and can lend themselves to interesting compositions

                            Background can make a big difference. 
                              Bobtail squid are often on sand, but  this one settled on coralline algae and the complementary colour is a good contrast.

                        Neither goby or coral would be so good on their own, but together they make the picture.

                            The shrimp is aligned to good effect with the lines on the back of a sea cucumber.

                        A lovely arch makes a natural window. Get your buddy to swim at an opening to provide a strong focal point.

                              An appealing image can be very simple – e.g. just light and weed.
