Collecting hanneloreae. Photo courtesy of Peter Tirbak.

Given as small rivulets in rainforest swamps. The type locality was described as being a marshy area belonging to the Nyanga River drainage at an elevation of 400 metres above sea level.

Mogens Juhl sent me an E-mail stating that he collected this sp. in abundance at GJS 00/14 - Malinga. Water temperature was 21·1 C, pH 5·9 and conductivity 1 microseimens. This location had a depth of only 2 cm. Also found were many small barbs and a new (?) Ctenopoma from the Ct.nanum-complex.

Distinguishing Characteristics Dorsal & anal fins show wide marginal (yellow) & submarginal (red) bands.
Colour/Pattern Variability Probably low.
History

Discovered by Ed Pürzl & Otto Hofmann in June 1985 close to Malinga in the centre of the Du Chaillu Massif. This collection code was GHP 85 / 11.

Breeding Notes

BKA newsletter No. 399, December 1998 has an article by Angel Cabrera on breeding GEB 94 / 20. Fish needed to be maintained in clean water & not crowded or they became sensitive to velvet. He did not use salt with these fish. Water temperature was 20-22°C, pH 6-6·5, GH 2. Natural light was used.
Spawning began at 8 months of age. First eggs were all fungussed. Spawns at 9 months were more fertile.
Bottom mops were used. Some males were quite aggressive. He did try 4 females & 3 males in a breeding set up & this caused males to fight. Eggs took 2-3 weeks to hatch in water. He did receive eggs in peat which arrived well so it's possible to semi dry them until eyed up. Newly hatched fry took newly hatched brine shrimp & microworms.

Remarks

It may be that this species is territorial in nature as males can be aggresive to each other.
