Some people seek out sharks and big animals, others get down and dirty in the muck for tiny, exotic critters. But all around us when we are diving are the “ordinary” reef fish that seem to get a bit overlooked. This is to celebrate these fish who are just as beautiful in their way as the big and the small. Here are just a few of this vast community. Hawkfish Forster’s, freckled or black-sided hawkfish (Paracirrhites forsteri). There are at least nine different types of hawkfish. This mainly solitary ambush fish is seen perched on coral stands or hard surfaces waiting to dart out and grab small fish or crustaceans. It is common on reefs from East Africa right across to Japan and Australasia. It is great for photography because it sits very still. It will only swim away when spooked, giving photographers the chance to practise a very slow approach so as to get as near as possible. Damselfish Sergeant major (Abudefduf saxatilis). Damselfish are absolutely everywhere. They have a variety of specialised roles as territorial algal farmers, planktivores or partners living commensally with sea anemones, the clownfish. This is a sergeant major defending its nest in a small hole in a vertical wall, and he is side by side with many other similar nests. The eggs can often be clearly seen on hard surfaces, which the fish aerate and defend from predators. Parrotfish and Trumpetfish Stoplight parrotfish (Sparisoma viride). There are at least 100 species of parrotfish across tropical coral reefs. They spend up to 90 percent of their day nibbling and cleaning the reef. This is important as many reefs are being smothered by algae because too many herbivores have been fished out. They also excrete fine white sand – lots of it. Yes, that idyllic, white sandy beach is likely parrotfish poo – sorry! They are also very garishly dressed and a big part of what makes reef diving such a colourful experience. In this picture a Caribbean trumpetfish (Aulostomus maculatusis) is shadowing the parrotfish, using it for cover while it hunts for food. SDOP
