African Starry Night Eel (Mastacembelus frenatus)


A medium sized, beautifully marked species of spiny eel, the African Starry Night or Longtail Spiny Eel is found in Central Africa, where it ranges from the Congo River Basin to several of the Rift Lakes as well as lake and riverine habitat in the surrounding areas. Hardy and more outgoing than many of their relatives, these fish make a unique addition to medium to large aquariums and will generally do well with any fish too large to become a meal. Like most spiny eels, they can be a bit slow to feed at first, so care should be taken to ensure they are getting enough food. Frozen bloodworms are usually accepted readily.
