Common name: twobarred goatfish
General information
The Twospot Goatfish, scientifically known as Parupeneus insularis, is a vibrant and active species that adds both color and dynamism to a saltwater aquarium. Its most distinguishing features are the two black spots at the base of the tail fin and its long, whisker-like barbels used for sensing food in the substrate.
This species is not as common in the aquarium trade as some other goatfishes, but it is appreciated for its interesting behavior and the unique touch it brings to a tank setup.

Care
Twospot Goatfish are relatively hardy and can adapt to life in captivity if provided with a spacious tank that mimics their natural environment. They require a sandy substrate for foraging and a variety of hiding places among live rock. These fish are active swimmers and need ample space to roam.
Their diet should include a mix of meaty foods such as shrimp, squid, and marine fish flesh. It's important to feed them multiple times a day due to their active foraging nature.
Reproduction
In the wild, Twospot Goatfish are known to spawn in groups, releasing eggs and sperm into the water column. However, breeding them in captivity is quite challenging and not commonly achieved by hobbyists.
Habitat
Parupeneus insularis is found in the tropical waters of the Indo-Pacific region. They are typically associated with coral reefs and sandy bottoms where they can use their barbels to search for invertebrates to eat. They are often observed at depths ranging from shallow waters to about 30 meters.
Geographically, they are distributed from East Africa to the central Pacific, including the Red Sea, Hawaii, and the Marquesas Islands.
