his factsheet for March 2014 follows on from Februarys
notatus) in that we
stick with the Mochokidae family and concentrate on
a lesser known genera, Euchilichthys. Not
often seen in aquaria but there are, according to
Fishbase and other literature, five species in this
genus, our factsheet of the month candidate, E.
guentheri, E. astatodon, E. boulengeri,
dybowskii and E.
Not very often
encountered in the trade and like the Chiloglanis
species they possess a sucking disc on the mouth
and so could resemble their Loracariid cousins from
South America. They differ from Chiloglanis in
having 1/6 soft dorsal rays, eye with a free border,
vertebrae 37 (16+21) and 8 branchiostegal rays.
This genus is found in
the Congo Basin in Africa and our subject is wide
spread and found in the lower courses and down to
drainage in Zambia.
The type locality is the Stanley
Pool, which is now called Pool Malebo, at Kinshasa.
Bangweulu and the Congo drainage
Aquarium care would be a tank
with a good water movement where they sometimes rest
in the flow. Provide hiding places such as bogwood,
stones and caves. The bogwood could be as tall as
to reach the water surface so they can take in the
current at a high level. In their natural habitat
they will graze on rocks and the living organisms
such as Aufwuchs. Try to keep the p.H. of
the water to the high side of acidity and over (6.5
- 7.2) as they will tend to shed mucus and become
lethargic if kept in too acidic conditions. Regular
water changes are a must to keep this catfish in optimal
River basin, down to the Bangweulu drainage system.
Type locality: Stanley Pool.
Flattened head with the skin
covered with small papillae and an elongated body.
Caudal fin is forked and pointed with the lower lobe
longer. Sucking disc is oval with a moderately long
upper jaw with two pair of very short mandibular barbels
and one pair of maxillary. The short adipose fin starts
behind the start of the anal fin.1/6 soft
dorsal rays, eye with a free border, vertebrae 37
(16+21) and 8 branchiostegal rays
Body dark brown with black
spots on the anterior parts with a bluish caste.

Peaceful but adults are territorial

the breeding of this species.
Vegetable food such as algae
tablets, flake and tablet food and live/frozen foods
such as Daphnia and Tubifex.
Anal fin:The median, unpaired, ventrally located fin
that lies behind the anus, usually on the posterior
half of the fish. Adipose fin : Fleshy finlike projection
without rays, behind the rayed dorsal fin.

primary rayed fin(s) on top of the body. Mandibular barbels: Pertaining to
