Care
French Grunts require a spacious tank with plenty of swimming room and hiding places. They are social fish and do well in groups, so consider keeping them with other peaceful species. They are omnivores and will accept a variety of foods, including frozen, live, and flake foods. Consistent water quality and parameters are crucial for their well-being.
Reproduction
In the wild, French Grunts are known to form large spawning aggregations. They are pelagic spawners, releasing eggs and sperm into the water column. While breeding them in captivity is challenging, it is not impossible for experienced aquarists with the right setup and conditions.
Habitat
Native to the Western Atlantic Ocean, from South Carolina to Brazil, including the Gulf of Mexico and the Caribbean Sea, French Grunts are typically found in shallow reefs and seagrass beds. They prefer areas with plenty of cover and are often seen during the day in large schools hovering above the reef, retreating into the reef's crevices at night.
