Fish offer a quirky perspective when they are photographed head-on. This vantage arises due to a fish's curiosity, aggression, shyness or cleaning tendencies... and then there are lionfish who just hang-out without a care in the world.
Bass, hamlets, butterflyfish and squid are in the curious camp and typically approach the camera to check you out to say hola.

Damselfish fall squarely in the aggression camp, protecting their share of the reef. They make rapid, strafing approaches and try to nip you if you get too close, offering a multitude of photo-ops.

Eels may look aggressive, but are usually a combination of shy and curious. Those teeth are still intimidating when they open their mouths for respiration.

Encountering a cleaning station is a good way to capture a mug-shot of a fish cleanee or cleaner. Intermediate angelfish still come near for a look after their juvenile cleaning days are over.
