Chasmocranus brevior Eigenmann, 1912

Etymology = Genus

Other Sources:

Search  Fishbase  Catalog of Fishes  Global Biodiversity Information Facility  FishNet2  iNaturalist

Relevant Information:

Rather rare (7 to 8 specimens known) maybe due to the very specialiced biotope in which Chasmocranus longior might be present. It is therefore poorly identified, also considering that the original description, rather poor, identifies it only in comparison with C. longior starting from the size of the adipose fin and the more pointed caudal fin.

Common Name:

None

Synonyms:

Heptapterus brevior

Family:

Heptapteridae

Distribution:

South America: Mana and Marowijne/Maroni river basins, and Potaro River.

Size:

8.0cm (3¼ins)

Temp:

24-28°C (75-83°F)

p.H.

6.0-7.5.
