Ctenops nobilis
Ctenops nobilis, McClelland, 1845


Origin: India; Brahmaputra region, and Bangladesh.

Etymology: Nobilis(L) means known, recognisable.

Synonyms: Osphromenus nobilis, Day, 1878.

First import: Germany, 1912, by Kropac.

Description:See picture.

Care: Difficult. Neutral to slighltly alkaline water, well filtered, although the fish dislike current. Water should be soft to medium hard, temperature in the lower region, and pure. Frequent small waterchanges are beneficial. Large tank(Min 100 cm)with lots of floating plants, plants, and driftwood. This species is very sensitive when kept in bad conditions, and easily contracts velvet, mouth fungus, and costia in such a case. As soon as something is remotely wrong, the fish will show their discomfort by clamped fins. Ctenops nobilis are very aggressiv towards their own species, but can well be kept with other fish that like similar conditions.

Temperature: 20-24 degrees.

Feeding: All food is taken, but usually only from the surface, and in the middle water regions. The fish prefer live food, especially insects, small shrimp(Mysis)and mosquito larvae, but can be taught to eat other foods.

Size: up to 10 cm.

pH: 6.0-7.5

Breeding: Prior to breeding a small bubblenest is sometimes made by the male. The fish will breed near the surface, and the female will produce an egg packet which is fertilized by the male. The female will collect the eggs, and spit them out in front of the male, who will pick up the eggs. Mouthbrooding period around 11-14 days, after which 40-100 fry are spat out by the male. Fry are approximately 6 mm large, but should be fed with infusoria for the first period.

Sexual dimorphism: Females have a marbled appearance, males have a brown ground color with dark points on the sides.(The picture shows two males)

Prices: Netherlands: 7€

Additional: Very rare fish, hardly ever available. The fish is listed as critically endangered in Bangladesh.
