Description
Sunset Grouper – Epinephelus fasciatus
Overview:
The Sunset Grouper, also known as the Blacktip or Redbanded Grouper, is a striking predatory fish recognized for its reddish-orange body accented with vertical dark bands and bold fin markings. With its powerful build and vivid coloration, it makes a dramatic display in large marine aquariums.
Origin:
Widely distributed throughout the Indo-Pacific, from the Red Sea to the central Pacific Ocean.
Feeding:
Carnivorous – feeds on meaty marine foods such as shrimp, squid, fish, and other protein-rich offerings. Should be offered a varied diet of fresh or frozen seafood.
Tank Mates:
Best kept with large, robust tank mates such as triggerfish, large wrasses, and other groupers. Not suitable with small fish or invertebrates, as they will be eaten.
Aggression:
Highly aggressive and territorial – should only be housed with other large, equally assertive species in a very spacious tank.
Experience Level:
Advanced aquarists – requires a large system, excellent filtration, and careful selection of tank mates.
