Yellow Goatfish
The Yellow Goatfish (Parupeneus cyclostomus), or goldsaddle goatfish, is a hardy, active sand-sifting predator — coral-safe, but it hunts small fish and invertebrates.

Yellow Goatfish
The Yellow Goatfish (Parupeneus cyclostomus), better known as the goldsaddle goatfish, is an active, characterful reef fish — frequently seen in a striking bright-yellow morph as well as more muted forms, and instantly recognised by the pair of long sensory barbels under its chin. It uses these "whiskers" to probe sand and crevices for prey, working tirelessly across the bottom. Hardy and engaging, it is a great fish for a large fish-focused aquarium, though its size and predatory diet need to be planned around.
Watching it sift the substrate with its barbels is one of the pleasures of keeping it.
Natural Habitat & Origin
Parupeneus cyclostomus is widespread across the Indo-Pacific, where it ranges actively over sand, rubble and reef, using its barbels to detect and dig out small invertebrates and fish. It is a roving hunter that covers a lot of ground.
In the aquarium it wants open sand to forage over, rockwork for structure, and plenty of swimming space for an active, sizeable fish.
Care Requirements
Maintain stable marine conditions: salinity around 1.024–1.026, pH 8.1–8.4, and a temperature of about 24–26°C (75–79°F). Reaching up to about 50 cm (20 inches), it is a large, active fish that needs a big tank — on the order of 570 litres (around 150 US gallons) or more — with an open sand bed for natural foraging. It is hardy and adaptable given the space it requires.
Diet & Feeding
The Yellow Goatfish is a carnivore that hunts small invertebrates and fish in the wild, sifting sand with its barbels. In the aquarium offer a varied meaty diet — frozen mysis and enriched brine shrimp, chopped seafood and quality marine pellets — and an open sand bed lets it express its natural sifting behaviour. Feed once or twice a day; it is an active, enthusiastic feeder.
Behavior & Temperament
This is a semi-aggressive, active fish that is generally peaceful toward similarly sized tankmates but will eat small fish and invertebrates and may bully smaller fish. It is best kept singly or with robust companions in a large tank. It spends its day roving and probing the substrate for food.
Tank Mates
House it with robust marine fish of similar or larger size — tangs, large wrasses, angelfish and similar. Avoid small, timid fish. It is coral-safe, but as an active hunter it will eat ornamental shrimp, small crabs and small fish, so keep it only in systems without prized small mobile invertebrates or tiny fish.
Breeding
Parupeneus cyclostomus is a pelagic spawner and is not bred in the home aquarium; trade specimens are wild-collected.
Common Health Issues
The Yellow Goatfish is hardy but, like all marine fish, can be affected by marine ich (Cryptocaryon irritans) and marine velvet (Amyloodinium ocellatum), particularly when stressed. Quarantine new arrivals, keep water quality stable, and provide an open sand bed. Mindful of its size and appetite for small fish and invertebrates, it is otherwise a hardy, active and fascinating fish for a large marine aquarium.
