General Description
The French grunt (Haemulon flavolineatum) belongs to the Haemulidae family, known for predatory fish that primarily feed on benthic crustaceans, worms, and fish. This species can vary significantly in appearance from youth to adulthood, with distinct differences observed. It falls under the category of Haemulidae, specifically under the Haemulon genus. French grunts can reach a maximum size of approximately 30.0 cm.
Aquarium Suitability
Considered suitable with care, the French grunt demands a large aquarium, especially when fully grown. This fish grows rapidly with proper feeding but requires a tank of at least 1000 liters in size. Due to their diet that includes shrimps, crabs, small bivalves, and snails, caution should be taken when housing them with crustaceans and other small marine creatures.
Care and Hardiness
The French grunt is described as hardy but requires frequent feeding, several times a day, particularly when recently introduced. They are known to consume a substantial amount of food, necessitating an aquarium equipped to handle this heavy feeding load. Providing ample hiding spots, like live rocks, is essential for their well-being.
Reef Suitability
Reef safe with caution, these fish can be housed in a reef aquarium if proper care is taken. However, due to their predatory nature, they may pose a threat to smaller invertebrates within the reef environment.
Aquarium Setup
For optimal care, the aquarium for French grunts should have sufficient swimming space, as they enjoy free movement. Incorporating hiding places and live rocks within the setup is crucial for their comfort. Maintaining water conditions with a pH range of 8.1-8.4, a temperature of 22.2-25.6°C, and a specific gravity of 1.020-1.025 is vital for their well-being.
Behaviour
French grunts are mostly peaceful but may exhibit aggression towards similar species. They can be kept singularly or in groups within an aquarium setting, adapting well to either lifestyle.
Feeding and Diet
These fish require a varied diet, including larger crustaceans, other invertebrates, and small crustaceans like krill, mysis, and artemia. It is important to ensure a nutritionally balanced diet to support their health and vitality.
Habitat and Distribution
French grunts are commonly found in the Mexican Gulf and the West Atlantic. Their natural habitat consists of coastal regions with rocky substrates, where they can feed on a diverse range of marine organisms typical to their diet.
