Monodactylus argenteus

Datasheet

General Description:The Mono Argentus, scientifically known as Monodactylus argenteus, is a member of the Monodactylidae family, characterized by their unique shape and reflective skin. These fish are commonly referred to by various names such as Silver moony, Silver moonfish, and Diamondfish. They originate from the Indo-West Pacific region, spanning from the Red Sea and East Africa to Samoa and Australia, typically inhabiting the freshwater tidal zones like the Mekong delta.

Aquarium Suitability:Considered suitable for aquariums with caution, the Mono Argentus demands specific care due to its requirements. It is essential to provide an environment that mimics its natural habitat, with plenty of hiding spots, macroalgae, and dim lighting to prevent the fish from swimming into the glass when startled.

Care and Hardiness:With an average level of hardiness, these fish are best acclimatized when introduced as juveniles. They are known to be sensitive during transportation and exhibit color changes when frightened, often becoming pale or brownish. Frequent feeding and a varied diet are crucial for their well-being, as they are heavy eaters and require ample space for swimming.

Reef Suitability:Reef safe with caution, the Mono Argentus can be kept in a reef aquarium under careful observation due to its behavior and demands.

Aquarium Setup:For optimal care, a tank size of at least 500 liters is recommended, along with stable water conditions including a pH range of 8.1-8.4, a specific gravity of 1.020-1.025, and a temperature range of 22.2-25.6°C. Providing larger crustaceans, macroalgae, and small crustaceans in their diet is vital for their nutrition and well-being.

Behaviour:These fish are mostly peaceful but may display aggression towards similar species, making it important to monitor their interactions in a communal tank setting. They can coexist with their own species, provided they are introduced simultaneously.

Feeding and Diet:The Mono Argentus thrives on a diet consisting of larger crustaceans like shrimp and crabs, macroalgae such as seaweed or nori, and small crustaceans like krill, mysis, and artemia. They require frequent feeding at least a couple of times a day to meet their nutritional needs.

Dimorphism:There is no specific information on dimorphism for the Mono Argentus, but they have been successfully bred in captivity, making captive-bred specimens available in the aquarium trade.

Habitat and Distribution:In their natural habitat, these fish are found in the brackish waters of the Indo-West Pacific region, ranging from the Red Sea and East Africa to Australia. They are known to inhabit freshwater tidal zones like the Mekong delta but can adapt to salinity levels equivalent to a specific gravity of 1.026.
