he Doumea genus belongs to the Doumeinae
subfamily with D. typica being the type species
with the holotype being collected in the Doumé
Falls, Gabon. At the moment (2022) there are nine
described species including our factsheet of the month,
D.angolensis Boulenger, 1906, D. chappuisi
Pellegrin, 1933, D. gracila Skelton, 2007,
D. reidi Ferraris, Skelton & Vari, 2010,
D. sanaga Skelton, 2007, D. skeltoni
Ferraris & Vari, 2014, D. stilicauda
Ferraris, Skelton & Vari, 2010, and D. thysi
Skelton, 1989. A few of these species can be told
apart from the length and proportion of the caudal
peduncle. All of these species are not very well known
in the hobby.
These catfish are
slim and elongated and possess bony projections (plates)
that radiate from the vertabrae reaching all the way
to the skin. The projections expand over the skins
surface, forming a shield that in some species covers
much of the body. They lack a swimbladder so they
tend to avoid open waters.
A Lower Guinea
endemic, known from Gabon and Congo in the Biguilé
River to the Louémé River, widespread
in the Ogowe basin. Coastal and other eastern rivers
from Cameroon to Congo.
River basin and coastal rivers from Cameroon
to Congo. Type
has most recently been assessed for The IUCN
Red List of Threatened Species in 2009 and
is listed as Least Concern. The preferred
habitat of this generaare
the upper courses of the rivers as they are
rheophilic (an organism that prefers to live
in fast moving water).
River basin and coastal rivers from Cameroon to Congo.
Type locality: Doumé (rivière
Dorsal spines (total): 0;
Anal spines: 0. Diagnosis: gap between supraoccipital
process and nuchal shield narrow, not greater than
width of supraoccipital process; postorbit 40-50%
snout length; caudal peduncle long (3-3.9 times in
SL), slender (length 14.3 times depth) and depressed.
Brownish above and whitish
to yellowish below. A light line marking the lateral
line runs through from the operculum to the caudal
peduncle. Six pairs of light brown saddle patches
adorn the back, first behind head, pre and post
dorsal base, pre and post adipose base and at caudal
Care & Compatibility
Not a well known species and
genera but good aquarium husbandry with regular water
changes and good oxygen flow should suffice.
Classed as "Epibenthic"
which would entail these catfish grazing in flowing
water. Mosquito larvae, tablet foods and any foods
which would lie on the top of the substrate should
be the feeding norm for these catfish.
fin:The median, unpaired,
ventrally located fin that lies behind the anus, usually
on the posterior half of the fish.
Caudal peduncle: The narrow part of a fish's
body to which the caudal or tail fin is attached. Dorsal fin:The
primary rayed fin(s) on top of the body. Epibenthic:
Refers to organisms that live on or just above the
bottom sediments in a body of water. These organisms,
many of which support commercial and recreational
fisheries, tend to forage on the creatures that live
in or on the sediments.
Nuchal shield: Area between the skull and
dorsal fin. Swimbladder:
The air sac that gives fish
buoyancy and balance. Acts as sound resonator in some
bone at the back of the skull, usually with a crest.
From Doumé, a locality in Congo (Africa).
