Care
Mexican Hogfish are relatively hardy but require a spacious tank to accommodate their size and active swimming habits. They can grow up to 30 centimeters (12 inches) in length, so a larger tank is necessary. These fish are not reef-safe as they have a tendency to nip at small invertebrates and may eat ornamental shrimp and crabs. A varied diet of meaty foods such as shrimp, squid, and fish flesh is essential for their health.
Reproduction
In the wild, Mexican Hogfish are protogynous hermaphrodites, meaning they start life as females and can change to males as they mature. In the aquarium, breeding is rare, but understanding their reproductive behavior can help in managing social dynamics within the tank.
Habitat
Native to the rocky reefs and slopes of the Eastern Pacific, from the Gulf of California to Peru, including the Galapagos Islands, Mexican Hogfish are typically found at depths ranging from 3 to 30 meters. They prefer environments with plenty of hiding places and open swimming areas.
