Flashlight Fish (Anomalops katoptron)

The Flashlight Fish or Anomalops katoptron gets its name from its glowing smile that is cause by bio-luminescent bacteria in organs below each eye. This glow will often be white, but will also turn a blue or yellowish coloration depending on the fish. The Flashlight Fish actually has the ability to turn this light on and off when needed! They will use their light to attract prey, to communicate with one another, and to cause a diversion for potential predators. This remarkable attribute makes this saltwater fish a favorite for advanced aquarium owners.
Also known as the Lantern Fish and the Twofin Flashlight Fish they have a black body with a blueish tint on their caudal and dorsal fins. Growing to about 9" in length, this fish requires an aquarium of at least 125 gallons with the following water conditions, 72-78° F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025. They can be kept with other nocturnal fish including Pinecone Fish, Squirrelfish and Cardinalfish. They need plenty of hiding spaces and low lighting to set the mood.  You can check out the Flashlight Fish underwater in the video below.
