The species of fish producing this light is a remarkable example of symbiosis. The light is generated by a group of organisms living within the fish, including symbiotic bacteria. These bacteria require a certain environment to stay alive, so the fish has an organ that it specifically designed to house them. Moreover, these bacteria are crucial for the biological processes of the fish, allowing it to survive and thrive. Furthermore, the use of the light organ in the fish’s communication, defense, and foraging is a testament to the remarkable adaptation of this species. The presence of the light organ also serves as a reminder of the importance of symbiosis in nature.

This nocturnal fish is well suited for the specialized aquarium that contains other nocturnal fish such as similar sized fish, squirrelfish, big eyes and cardinalfish. A low light tank or a tank with numerous hiding places is ideal. A small group of these fish work best, as they usually will adjust more quickly and take food easier when they are maintained together. Rarely aggressive among themselves or to other fish in the aquarium, this species fares best with very passive tank mates. These fish are extremely sensitive to copper sulfate and should never be exposed to this medication.
