Ctenopoma nanum, Günther, 1896

Origin: Camerun, Gabon, Congo, Kongo. Here the fish occur in fast flowing waters with slightly acidic soft clear water with an average temperature of 25 degrees. They are usually found in forests, below vegetation and between roots.

Etymology: nanum means dwarf

Synonyms: Anabas maculatus, Boulenger, 1882, Anabas nanus, Boulenger, 1916.

First import: Germany, 1933, unknown by whom. First bred by Hans Joachim Richter.

Description: See picture, very variable species.

Care: Aggessiv species, best kept in pairs in a large species tank(minimum 70 cm), or together with larger robust fish. Shy fish that are rarely visible in well planted tanks, especially if brightly lit. A dark soil, lot's of hideouts and some floating plants are recommended. Soft, slightly acidic to medium hard water, combined with frequent waterchanges and well filtered(current!).

Temperature: 22-25 degrees

Feeding: Live and frozen food, sometimes also flake food.

Size: 7.5 cm, females smaller, 6.5 cm.

pH: 6.0-7.5

Breeding: Bubblenester, difficult to breed. The male will build a bubblenest between floating plants. Up to 1000 eggs are laid by the female, which should be removed immediately afterwards, since the male will become extremely aggressiv after mating. The eggs float, and hatch in a day. After three days the fry will be free swimming, and at this stage the male should also be removed.

Sexual dimorphism: Males are more colorful and have elongated dorsal and anal fins.

Prices: 10-15€ a pair.

Additional: Actually first described by Boulenger in 1882 as Anabas maculatus. In aquatic literature often pictures of Ctenopoma fasciolatum are described as Ctenopoma nanum.

Picture references: Picture 1: Andrew Smith.
