Common name: Comet

General information

The Marine Betta, also known as the Comet or Comet Marine Betta, is a species of fish that is highly prized in the aquarium trade for its unique appearance and behavior. Its scientific name is Calloplesiops altivelis. This fish is known for its deep blue to black body adorned with white spots that resemble a starry night sky, and its long, flowing fins that add to its celestial appearance. The Marine Betta has a distinctive eye spot on the dorsal fin, which is used to confuse predators and is a classic example of Batesian mimicry.

Care

Marine Bettas are relatively hardy and can be a good choice for intermediate to advanced aquarists. They require a tank with plenty of hiding places and a cave-like structure where they can retreat. These fish are nocturnal and prefer dim lighting. They are carnivorous and thrive on a diet of live or frozen foods such as brine shrimp, mysis shrimp, and small fish.

Reproduction

In the wild, Marine Bettas are cave spawners, laying their eggs in protected areas. In the aquarium, breeding is rare, but with the right conditions, it is possible. The male guards the eggs until they hatch.

Habitat

Calloplesiops altivelis is found in the Indo-Pacific region, from the Red Sea to South Africa and east to the Line Islands. They inhabit reef environments, often in caves or under ledges, at depths ranging from 3 to 50 meters.
