Monodactylus sebae

17. February 2021

The African Mono is widely distributed along the tropical Atlantic coast of Africa. As a completely euryhaline fish, it can freely change between fresh, brackish and seawater; it prefers to stay in brackish water. In its native range M. sebae is a common fish and is caught there for food. In the past, aquaristic needs were met by wild-caught fish from Lagos Bay, Nigeria, but for decades this species has only been available as offspring from Southeast Asia. 

M. sebae was one of the first marine fishes to be successfully reared in the aquarium. First breeding reports date back to 1968, planned breeding succeeded since the 1970s. The animals are free spawners without brood care, the spawn swims around during development, external sex differences are not known.

With a maximum length of 25 cm (but mostly around 15 cm, the animals are spawning at about 10 cm at the age of about 1 year) Monodactylus sebae is not a small fish, furthermore they are fast swimmers and should be kept in a troop (from 8 specimens upwards). So they require a correspondingly large aquarium. A value of 3-4 g/l has proven to be the ideal salt content. Monos are carnivores, which can be well fed with all common frozen and live foods. Dry food is accepted, but should not be used as a sole food. Monos like it warm, the water temperature should be between 25 and 28°C.
