Mali - Collected in 1982 by a German guide whilst escorting a group of tourists in Mali. This population was reportedly prone to velvet & needed the addition of salt to the water.

Milestone 56 - At the Collingham auction on September 10th 1972 a number of Scotsmen donated to the BKA a bucket containing 12 pairs collected at Milestone 56, Accra to Ade road, Accra Plain, southeast Ghana.

Photographs of Kluge's strain & Clausen's Sogakofe collection can be found in ROTOW 1 pp 421-422.

Mangu District of northern Togo said to be located between Kadjamba & Bogo-Moba & Panpamba to Nacjaba in the north.

Kluge's collection of 1959-60 gave the following data from a point between Takoradi & Alenda on the Tano River - water temperature 23-27°C, pH 5·7, German Hardness 1·5.

Ahl described this sp. from 7 specimens (probably males measuring 25-30 mm, according to Scheel) collected from the Mangu District of northern Togo said to be located between Kadjamba & Bogo-Moba in the south & Panpamba & Nacjaba in the north (ROTOW 1 p 421). Scheel considered this to be in an area of dry savannah containing many temporary small river systems of the Kari-Oti-Volta drainage of northern Togo.
Ahl based his description of the seperate genus Fundulosoma on the structure of the teeth.
There has been confusion in the past with Fp.walkeri. In 1934 Pellegrin reported walkeri from Fada-N'Gourma, Upper Volta close to the type locality for thierryi. This collection was most probably thierryi. The description of walkeri was based on females whereas thierryi was based on males so a colour comparison between males was not possible.
In 1954 Daget redescribed thierryi using material collected in rice fields at Diafarabé Upper Guinea, situated on the Niger River, southwest of Mopti. An article in BKA newsletter 97, Sept.1973 by Radda stated that he called these fish A.walkeri.
Between 1959-1960 a fish described as 'Small Aphyosemion from Ghana' was introduced which was collected by Kluge 'near the road between Takoradi & Alenda, on the Tano River about 30 kms from the western end of this road' (ROTOW 1 p 422). This form was distributed to aquarists in Germany & proved a popular introduction.
Although I can find no binding article these may be the same fish which were distributed by the importer Heinrich Espe of Bremen, Germany who received this sp. in late 1959. These were propagated by Foersch, Scheel & others.

Known to have been in Holland in June 1960 (probably the first time in this country) when A.J.De.Looze received eggs from München, Germany. The June DATZ contained a small article on the sp.

Foersch observed & photographed a fish Radda referred to as 'Ghana Aphyosemion' in 1961. These were later identified as Fp.walkeri (or to be more accurate, Boulenger's Fundulus walkeri of 1911). These are almost certainly referable to 'thierryi' in modern times.
Perhaps the first introduction into the USA was by Foersch who sent eggs to Rosario LaCorte around this time. From these eggs 'several hundred fry' emerged.

Pellegrin, in 1934, also examined 10 specimens from Fada N'Gourma, Upper Volta, as Fundulus walkeri.
In BKA newsletter No.97, September 1973 Dr.A.C.Radda mentioned that this sp. had been imported into Germany from Ghana around 1963.Clausen collected thierryi in an affluent from a swamp near Sogakofe, Lower Volta drainage. Scheel maintained a male from this collection & mentioned that it 'corresponded in most details to Kluge's strain'.
On the 28th June 1970 an import arrived in the UK from David Blair together with Pro.kiyawensis. They also arrived in another shipment on July 10th 1970, again with Pro.kiyawensis. David returned home on the 15th September with more stoc of the sp.
1982. Collected in Mali by a German guide & distributed as Mali.

DATZ in June 1961 contained a reference to keeping eggs in slightly damp peat environment for 2 months.

Perhaps the first records of breeding this sp. (at least in the AKA) come from the Aquarium Journal of June 1961 where Rosario LaCorte bred them in a tank with a sand substrate. He recorded a 3 week incubation period in water. He noted that this sp. was slow to hatch, even for fully developed embryo's. He forced a hatch by adding microworm to the container.

In an article by A.J.Delooze in the above publication he mentioned a hatching where the fry were too small to take newly hatched brine shrimp. He went by motorcycle to a pond where he collected a large amount of infusoria which was taken by the fry. He had a large amount of females but noticed a male after 6 weeks.
Around this time he had eggs from Scheel.
These young grew on to form a breeding stock. He observed that they layed there eggs on the peat substrate & did not bury there eggs.

A breeding report in BKA newsletter No. 224, April 1984 concerning the Mali population stated that the pair were given a 3 gallon tank. pH 7·5, DH 12, water temperature 80°F. A half inch layer of peat was added to the tank base.
It was reported that this sp. hunt for eggs as part of there diet. On collecting the peat a total of 8 eggs were found. These were incubated on wet peat at 80°F. They started to eye up at 4 weeks. On hatching the fry were 3 mm & capable of taking infusoria on hatching. Newly hatched brine shrimp was added to there diet after 2 weeks.
Eggs were also collected from the parents tank from Java moss fully eyed up.

In BKA newsletter No.79, March 1972 an article appeared regarding social behaviour of this sp. (Ewing). The author found males territorial although females were not. The size of their territory was such that 15-20 males & 30-40 females could be safely maintained in a 24 x 18 x 6" deep tank. This number should be maintained & no attempt should be made to remove or add other fish.
Males can be quite aggressive & plenty of cover should be afforded the female/s.
