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.
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.
Bangweulu drainage system.
and the Congo drainage systems.
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.
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.
Peacfull but adults are territorial with conspecifics.
No reports on the breeding of this species.
No discernable differences.
Vegetable food such as algae tablets, flake
and tablet food and live/frozen foods such as Daphnia
