Apistogramma baenschi

Apistogramma baenschi
Inka Apistogramma
A Japanese aquarist called Karatsu introduced a special little addition to the hobby in 2002. He had found Apistogramma baenschi and given it the common name of the Inca cichlid. 
The discovery was made after Karatsu and some other Japanese fishkeepers had travelled to Peru and explored around the Rio Mayo near the town of Tarapato, catching specimens in small blackwater forest streams. 
Particularly unusual about the collection locality was its height — 800m/2,600ft above sea level — and the surroundings more closely resembled those of the Asian rainy forest mountains than typical lowland South American forests. 
A couple of years later, Dr Uwe Romer and co-authors described the species in a German aquarium magazine, naming it Apistogramma baenschi in honour of Romer’s publisher friend Hans Baensch. 
The basic body coloration of A. baenschi is yellow with three to seven contrasting black lateral stripes. They also have a small blotch at the base of the caudal fin. 
These dwarf cichlids are characterised by distinct sexual dimorphism and dichromatism — so males and females differ markedly in colour and size. Males have a deep body, massive snout with prominent fleshy lips, elongated rays at the front of the dorsal fin and a blood red edge to the tail. 
Females are smaller and less colourful, their dorsal fins are not elongated and half to two-thirds of the pelvic fins are black. They also have a black spot at the base of the pectorals and this becomes prominent when they are brood caring, probably emphasising that they are territorial and aggressive.
