Monotaxis grandoculis, also called Humpnose Big-eye Bream, are widespread in the Indo-West and Central Pacific from the Red Sea and east coast of Africa, east to Hawaii, Oceania and southeast along the northern coast of Australia back to Reunion and Madagascar. The northernmost locality is the southern tip of Japan.
The basic body color of the Humpnose Big-eye Bream is usually a little lighter blue-gray to almost white ventrally. His mouth (lips) can have almost all colors from yellow to pink depending on the origin and age. The eye area is often yellow to orange, the fins usually have no distinctive features and are usually transparent or show only a slight tint. Juvenile animals usually have three to four clearly visible, dark, often almost black crossbars. On the lower half of the body it is often much brighter than the upper. Adult animals have the opportunity to show this crossbar as well, but this is rarely seen.
Monotaxis grandoculis are usually found in reefs or near reefs, but is also found in lagoons on sandy bottom or even more rugged rocky areas. Most often we see them in smaller groups between 50-100 animals move around the reefs.
Humpnose Big-eye Bream is a "night hunter", his diet includes clams, brittle stars, sea urchins, crabs, polychaetes, sea squirts and sea cucumbers. They can reach a final length of up to 60 cm, most individuals are not larger than 40-45 cm.
