Type Locality

102 km from Mékambo in the direction of Makokou in a marshy stream. Collected by Radda & Pürzl 1975.

Distribution

Northern Gabon, from Makokou extending eastwards towards northern Congo.

Habitat

Rainforest brooks of the Ivindo River drainage system.
See also A.georgiae under 'Habitat'. Collected with A.georgiae & A.cyanostictum by Roland Numerich in February 1987. He reported a 'very beautiful red form' from this biotope but none were brought back alive. BKA Killi-News No.296 (May 1980) contains a sketch of the biotopes & what was caught in each area. In this sketch A.punctatum is seen to inhabit small pools at the side of the main stream. These are most probably flood pools. These were visibly cloudy with a skin of golden red mould on the surface caused by the high iron content of the water. This is obviously why the fish were described as a'very beautiful red form'.

Distinguishing Characteristics Few red spots on the body, mostly in the upper half. Caudal fin has outer margins top & bottom of red but often these do not reach the outer vertical edge as a thick continuous band, petering out in this area.
Colour/Pattern Variability Medium
History

Discovered by Gaspers et al in 1971 at the type locality, however these fish were not used in the original description.

In 1974 Bochtler collected at this location then called G 10/74. These fish were used for the description.

J.Lambert was informed of a collection of fish under the name A.striatum ogoense from Makokou on the Ivindu River. He observed differences in the pattern & colouration between the 2 forms.
Radda also received material from Bochtler in January 1974 collected at Makokou, north western Gabon near to the Catholic Mission. These were considered to be similar to A.wildekampi & were assigned the name A.spec.aff.wildekampi in 1975.
It was later classified as a seperate sp. by Radda & Pürzl in 1977 as A.punctatum.
The Koulamoutou population is more southerly on the du Chaillu Massif.

Collected by Rudolf Kubeck in 2000 at Makokou.

Oliver Lucanus collected them in 2004 from a small stream in the Lobeke National Park, southeast Cameroon.

Breeding Notes

Regarded as a difficult species to breed. Water incubation 12-14 days. Young are slow growers taking 7-8 months to reach sexual maturity.

Tyrone Genade in BKA newsletter No.483, December 2005 reports breeding in water of 23-24°C. A mop & peat moss with a few plants added. No filtration but a small airline with a trickle of air. Water was changed at 25% weekly. Eggs were mainly found near the tie in the mop at the surface & a tie near the base.
He found spawning in temperature below that stated above were unproductive.
Eggs water incubated & floated on the spawning tank took 12-14 days to hatch. Many fry were seen to hatch prematurely but were free swimming in a day or two. Fry would accept crushed flake & granulate. Fry in the parents tank were not molested by the adults.
Eggs can also be stored on wet peat.

Diameter of Egg Around 1 mm.
