The Marine Betta (Calloplesiops altivelis) is also known as The Marine Commet. They have a dark brown to a blackish body with white spots evenly distributed over their entire length and an eyespot near the end of their dorsal fin. When fully displayed the fins give them a long oval-like shape. The Marine Betta has a unique swimming behavior, it will pivot its entire body while keeping its eyes stationary. This is thought to be a territorial display and way of using its false eyespot to confuse predators. It's at this swimming angle the eyespot is used to confuse predators into thinking that it is a moray eel. The Marine Betta has a somewhat shy nature, often preferring to hide in rock crevices by day light hours as it is nocturnal and requires hiding places to provide it shelter from bright lighting, whilst being much more active at dusk.
