Ultraslender Cichlid Steatocranus sp. 'ultraslender'

The Ultraslender Cichlid is a recently-described river cichlid native to fast flowing areas of Africa's lower Congo River.

As its name indicates, it is very slim despite being in the same genus as the Buffalohead or Humphead, S. casuarius. It grows to about 6cm long. The long dorsal fin is red on some.
