The Red Indian fish Pateocus fronto is a master of camouflage. They mimic fan sponges, especially red colours. They are slow moving and rely on sudden ambush to capture prey. Wide angle close up photography is good for these fish that remain still. You have to angle strobes in to get plenty of light onto the subject. However, the front of the strobes MUST remain behind the edge of the dome port or you will get flashlight exposure directly into the subject that ruins the photo. i.e. Strobes must be behind the plane of the dome port.
