[Ebook] 500 freshwater aquarium fish – Killifish – Blue Killifish (Aphyosemion filamentosum)

The males of some populations of this species, such as those from southern Togo, possess a great deal of blue on their bodies, hence one of the common names. Confusingly, some other populations from the same region are orange-red. Most populations from other locations contain varying amounts of blue, orange-red, and reddish brown.

• Livefoods preferred, but will accept other diets.

Aquarium

• As for A. australe, but water chemistry less critical. Temperature range: 72-77°F (22-25°C).

Breeding

• Ensure lowered water level, a thick layer of peat on the bottom, and subdued lighting. Introduce 1 male and several females. Eggs buried in peat. After spawning, remove peat and sgueeze gently to eliminate excess moisture. Store at around 72°F (22°C) for about 3 months, ensuring it does not dry out. After this resting period cover the eggs with aguarium water. Hatching will occur over a number of days.
