The monochrous gymnothorax is a lonely fish, which lives mainly in crevices and underwater caves. It can also be found in coral reefs or in shallow waters near the coast. The monochrous gymnothorax can reach a size up to a meter in length, although most individuals measure approximately 60 centimeters.

The monochrous gymnothorax is a fish that reproduces in spring and summer. The females lay eggs which they fix on solid surfaces under water, such as rocks or wrecks of ships. The eggs hatch about a week later, freeing larvae floating on the surface of the water. The larvae then undergo several metamorphoses before becoming juveniles resembling adults.
