his factsheet for March 2014 follows on from Februarys
(Synodontis
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,
E.
dybowskii and E.
royauxi
Euchilichthys
guentheri
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
the Bangweulu
drainage in Zambia.
The type locality is the Stanley
Pool, which is now called Pool Malebo, at Kinshasa.

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
condition.
