Family: Mullidae ยท Goatfish
Also known as: Gold Saddle Goatfish, Blue Goatfish, Yellowsaddled Goatfish, Moano
The Yellowsaddle Goatfish is one of the largest and most impressive members of the goatfish family, capable of reaching 20 inches in length in the wild. This species displays remarkable color variability, with individuals appearing in either a brilliant golden-yellow phase or a striking blue phase depending on their mood, habitat, and time of day. The yellow color phase features a bright canary-yellow body with a darker saddle marking, while the blue phase displays a vivid electric blue coloration. This ability to shift between dramatically different color states makes the Yellowsaddle Goatfish one of the most visually dynamic fish available to marine aquarists.
In the wild, the Yellowsaddle Goatfish is found on coral reefs and rocky substrates throughout the Indo-Pacific, from the Red Sea to Hawaii. It is a more aggressive predator than most goatfish species, actively hunting small fish and larger invertebrates in addition to the typical benthic organisms that most goatfish consume. It uses its long chemosensory barbels to probe crevices and substrate for hidden prey, and it has been observed cooperatively hunting with other species, herding prey toward each other in a remarkable display of interspecies collaboration.
Due to its large adult size and semi-aggressive temperament, the Yellowsaddle Goatfish requires a spacious aquarium of at least 180 gallons. It is not suitable for reef aquariums with ornamental crustaceans or small fish, as it will consume anything it can swallow. Despite these requirements, it is a hardy and adaptable species that acclimates well to captivity. Its dramatic color-changing ability and active behavior make it a centerpiece fish for large fish-only or FOWLR aquariums. It can be kept with other large, robust species that are too big to be consumed.
Yellowsaddle Goatfish are active carnivores and one of the more predatory goatfish species. They feed on small fish, crustaceans, and invertebrates in the wild. In captivity, offer frozen silversides, krill, chopped shrimp, squid, and sinking carnivore pellets. They have a hearty appetite and should be fed two to three times daily. Will also actively hunt and consume any small invertebrates in the tank.
The Yellowsaddle Goatfish is more aggressive than most goatfish species and will consume small fish and any invertebrates it can catch. It should only be housed with large, robust tankmates that are too big to be eaten. Compatible with large tangs, large angelfish, groupers, and triggersfish. Avoid keeping with small, peaceful species that would become prey. Can be kept with other large goatfish in very spacious systems.
Check CompatibilityYellowsaddle Goatfish are pelagic spawners that have not been bred in home aquariums. Their large adult size, predatory nature, and extended planktonic larval phase make captive breeding impractical for hobbyists.
