Silver and African Moonies (Monodactylus)

The Silver Moony is Monodactylus argenteus; the African Moony is Monodactylus sebae. Prepare appropriate brackish-water care for these fish rather than assuming that a juvenile holding condition defines their lifelong needs. Confirm the fish’s present holding conditions and plan an appropriate measured brackish-water system for its longer-term care.

Plan usable swimming and turning room for deep-bodied adults and an appropriate social group. Compare filtration, food and companions for the particular species. A small juvenile delivery grade or buying two fish does not establish that the aquarium has suitable adult capacity.
