I am struck here by the collections of Miss Kingsley. Who was she & how did she become involved in collecting fish to the extent of supplying Boulenger in the early 1900's?


History of the synonym Aplocheilichthys tschiloangensis (Ahl 1928)

Described from Landama, Cabinda, Lower Congo.

Breeding Notes

A report appeared in BKA newsletter No.87, November 1972 in which marine salt was added to the strength of SG 1·006. Eggs were laid in a bottom mop & were observed to be in clumps of 4-8. Eggs were taken out & incubated in a tub excluding light. Embryo development was apparent at 4 days with hatching ocurring between 18-22 days. Newly hatched fry were observed rarely to leave the water surface & swam awkwardly. Feeding presented problems as they seemed too slow to catch newly hatched brine shrimp. It was observed they were feeding from a surface scum.
The strength of the fry noticably increased around 12-14 days were they were able to catch brine shrimp.
Egg yield was observed at 25 eggs per day, per pair.

Diameter of Egg 'Approaching' 2 mm
Remarks

This sp. is particularly susceptible to velvet but will tolerate salt to brackish levels..
