Description
The Marine Betta, also known as the Comet, is a strikingly beautiful fish known for its unique, eye-catching patterns. Its body is dark black or brown with white spots, and it has a bright orange-red stripe running from its eye to the first dorsal fin. This species is nocturnal and tends to be quite shy, often hiding among the rocks during the day.
Reef Safe
Yes, but it may eat small fish and invertebrates.
Environment
The Marine Betta prefers a tank with plenty of hiding spots, such as caves and crevices, as it likes to hide during the day and come out at night. It also prefers dim lighting to mimic its natural habitat. The tank should have a tight-fitting lid to prevent the fish from jumping out.
Behavior
The Marine Betta is a relatively peaceful species that tends to keep to itself. It is nocturnal and prefers to hide among the rocks and crevices during the day, coming out to hunt at night. Despite its peaceful nature, it may eat smaller fish and invertebrates.

The one I received was eating right away but they are nocturnal so keep that in mind. They require caves and will stay in them essentially all day. Gorgeous fish tho and I personally love looking at the tank at night when everything has settled.
