Habitat

Small rainforest rivers, creeks & swampy areas, also forested savannah.

Distinguishing Characteristics Distinguished from E.chevalieri nigricans by a greater body depth. E.chevalieri nigricans is a thinner looking fish.
Colour/Pattern Variability The number of red spots in the unpaired fins can vary from many to being virtually non-existant. Body shape is a good indicator for this species.
History

Pellegrin, in 1904, described this species as Haplochilus chevalieri from 3 specimens collected at Brazzaville.

Poll rediscovered the species in 1939 in a collection originating from Stanley Pool.

Lambert, in 1961, suggested that E.chevalieri & E.nigricans were closely related & E.nigricans could be considered to be a subspecies of E.chevalieri.

The BKA had a small import consisting of 7 fish from Kinshasa around August 1972.

Breeding Notes

Geoff Wood put a breeding report in BKA newsletter No. 114, February 1975. He had difficulty when first breeding them in Zaire but painted the back & sides of the tank dark green & covered the top with brown paper. Peat fibre was added which was floating & sunken. The fish were fed ants & mosquito larvae & left undisturbed.
A few large eggs were found in these fibres which were removed to another container. Hatching occured in 18 days & the fry took newly hatched brine shrimp & microworm.
Growth rate was slow & he noted that at first they were patterned with dark blotches.
He considered them to be not very prolific & observed that in the wild they were not a common sp. being outnumbered by other sp.

Lays on top & bottom mops. I used rainwater for my wild fish & found them quite easy to breed. Some reports suggest they are more difficult. Eggs water incubate for around 14 days with sexual maturity around 7-8 months.

Remarks

This species is sensitive to nitrate poisoning so frequent water changes are required.
