Rosy Goatfish

General information

The Saddleback Goatfish, scientifically known as Mulloidichthys pfluegeri, is a captivating species that adds both activity and color to a marine aquarium. They are known for their distinct yellow fins and the characteristic 'saddle' marking across their back. These fish are part of the Mullidae family, which are known for their pair of chin barbels that contain chemosensory organs, allowing them to detect prey in the substrate.

Care

Saddleback 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 ample swimming space. A varied diet of meaty foods such as shrimp, squid, and marine fish flesh will keep them healthy and vibrant. It's important to note that they can grow quite large and may disturb smaller, more timid tank mates during their active foraging.

Reproduction

In the wild, Saddleback Goatfish are known to form large spawning aggregations. However, breeding them in captivity is quite challenging and not commonly done by hobbyists. They are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs.

Habitat

Native to the Western Atlantic, Mulloidichthys pfluegeri is commonly found in tropical and subtropical waters, from Florida and the Bahamas to Brazil. They inhabit coral reefs and sandy areas, often seen foraging in the sand for invertebrates during the day. At night, they are known to venture into open waters to feed.
