The Blue-spotted Grouper is an attractive member of the Cephalopholis genus, featuring a reddish-brown body adorned with vivid blue spots that make it a visually appealing addition to large marine aquariums. This medium-sized grouper reaches approximately 14 inches in captivity and is well-suited for experienced hobbyists.
In the wild, Blue-spotted Groupers inhabit coral reefs and lagoon areas throughout the Western Pacific, typically found at depths of 1 to 40 meters. They are solitary ambush predators that establish territories around coral formations and rocky overhangs, waiting patiently for small fish and crustaceans to wander within striking distance.
In captivity, this species adapts well to aquarium life and will readily accept a variety of frozen and prepared foods. It requires a tank of at least 125 gallons with plenty of caves and hiding spots. While it is generally less aggressive than many larger grouper species, it will still consume any tankmate small enough to fit in its mouth.
A carnivorous predator that requires a protein-rich diet. Offer frozen silversides, krill, shrimp, squid, and high-quality carnivore pellets. Feed every other day for adults and daily for juveniles. Vary the diet to ensure complete nutrition and prevent fatty liver disease.
The Blue-spotted Grouper is semi-aggressive and will prey on any fish small enough to swallow. Best housed with similarly sized or larger robust species such as tangs, large angelfish, triggerfish, and other groupers. Avoid keeping with small fish, ornamental shrimp, or delicate invertebrates.
Check CompatibilityBlue-spotted Groupers are protogynous hermaphrodites. They begin life as females and may transition to males as they grow. Captive breeding has not been achieved due to the species' complex pelagic spawning behavior and size requirements.
