History |
Lambert described this species in 1958 from 20
specimens caught in the Conakry - Dubreska district of Lower Guinee.
Roloff caught them in 1962 in Sierra Leone &
in 1965 supplied Scheel with material from Kenema.
In October 1967 (at the end of the dry season)
Kuschereitz re-discovered them 20 kms from Conakry in the direction
of Kindia. The water in this region was reported to be tinted red from
rich deposits of Bauxite in the earth. This collection probably became
circulated in the hobby as KCF 1.
Many populations have been discovered over the
years:-
Abuko & Battabut, Gambia. Both locations
are fairly close to each other. Other species found in the biotope included
Epiplatys bifasciatus, E.spilargyreus
& 'red' cichlids (possibly Hemichromis
sp.). Many people have caught them from these locations, amoung them
Frohlich in 1972, 1974 & 1977 & Rust in 1974.The Abuko population
was widely distributed in the UK in 1986.Quite large populations reported
to reach 8 cm in length.
Barmoi, Kenema, Makeni, Rokupr, Rotamp, Sierra
Leone. Collected by Roloff.

Breeding
Notes |
It has been reported that young fish prefer to
lay at the surface whilst older fish lay near the bottom.
Water incubation 13 - 21 days (some publications
state 17-29 days). Fry are small on hatching & do better with infusoria
for a few days. It can take 6 months or more for the young to reach
sexual maturity.
Anthony Pinto in BKA newsletter No.249, May 1986
gives a breeding report for the Gbessia population. The original stock
reportedly endured temperatures of 45-50°C whilst in transit for
4 days & survived.
The breeding water was 24°C, pH around neutral, DH 2. A few clumps
of peat fibre were added. It was noted that water changes are not appreciated
by the breeding fish & only 25% was changed every month. Males are
reportedly not hard drivers.
The majority of eggs were found in floating mops although some were
laid at the bottom of the tank. On average around 40 eggs per week were
collected. Young breeders were noticed to produce many infertile eggs
but this improved as the fish matured. Water incubation takes about
3 weeks & the fry are very small on hatching requiring infusoria
for the first few days.
Growth was fairly slow with the first signs of breeding attempts being
made at 3 months.
_________________________________________________________________
Michael McCarthy of the AKA kindly sent me a
report of his experiences with the Abuko population:-
'I've been keeping Script. geryi
'Abuko' and I initially had trouble with the eggs fungusing when water
incubating, once one went bad I would lose the entire batch in a couple
of days. The best solution I found was to store the eggs on peat fibre.
Eggs are then checked daily for a week and any bad eggs removed. The
eggs are stored for 18-21 days total at 23°C (at this point, they
should stand out clearly on the peat and even at the small size of the
eggs, they can be seen to be eyed up). The eggs can then be put into
a hatching container and will hatch out in 24-36 hours. This eliminates
staggered hatching associated with water incubating and greatly increases
the hatch rate. I've not noticed a skew in the sex ratio from this method,
nor belly sliders'.

Diameter

0.9
- 1.1 mm |
Remarks |
A rather shy species which likes to hide. If
given a large enough tank with plenty of plant cover they can be encouraged
to put in an appearance.
