Colombian Tetra (Hyphessobrycon columbianus)

Family: Characidae: Hemigrammus Clade

Common Name: Colombian Tetra

Origin and Habitat: Endemic (probably) to the Rio Acandi system, Colombia. Occurs in small slow-flowing creeks.

Compatibility/Temperament: Peaceful, though some report it may nip fins. A group of 6-8 or more may lessen this tendency; a shoaling fish, it should be in a group. It should not be kept with sedate species such as angels, discus or gourami due to its boisterous activity and aggressive feeding habits [see comments under Diet] but only with similarly non-aggressive characins, rasbora, small barbs, danio, catfish and loaches. A good dither fish for dwarf cichlids.

Colombian Tetra Diet

In it habitat, feeds on small invertebrates. Accepts prepared foods; frozen and/or live bloodworms, daphnia, artemia. A hearty and greedy feeder, it must not be overfed; it has been observed taking food out of the mouths of other fish.


Attains 7cm (approximately 2.5 inches).

Minimum Tank Suggestion

36 inches in length.

Water parameters for Colombian Tetra

Soft to medium hard (< 12 dGH), acidic (pH < 7) water, temperature 23-27C/73-80F.


In a well-planted aquarium that provides adequate swimming space, this is a very beautiful tetra. Dim light, achieved partially with floating plants, along with a dark background and dark substrate will allow it to sparkle. It remains in the middle reaches of the aquarium. The fish has a lifespan of 3-5 years.

The dorsal fin of mature males is slightly longer than females, and the latter is rounder in appearance. Fairly easy to spawn, and like most characins it is an egg scatterer. The eggs will be eaten if left with the parents after spawning unless they fall among thick plants in which case they will likely hatch and the fry appear without intervention by the aquarist.

This fish has been in the hobby for the past decade; originally it was known (unofficially) under the incorrect name H. ecuadorensis, which species is somewhat resembles. In 2002 the species was described as H. columbianus by A. Zarske and Jacques Gery. The spelling of the species epithet columbianus is the Latin form with a "u", not the Spanish with "o."

The genus Hyphessobrycon--the name from the Greek hyphesson [believed to mean "slightly smaller"] and brycon [=to bite]--was erected by C.H. Durbin in 1908 and presently contains more than 100 described species. The classification is deemed incertae sedis [Latin, "of uncertain placement"]. It was formerly considered within the Subfamily Tetragonopterinae, but Javonillo (2010) suggest that this subfamily should be restricted to species within the genus Tetragonopterus since they do not share physiological characteristics with species in other genera such as Hyphessobrycon.

Authors that have recently studied the systematics of the genus Hyphessobrycon have unanimously pointed out that the group is not well defined and its monophyly is yet uncertain. [A monophyletic genus is one wherein the species share a common ancestor, thus linking them together physiologically.] Mirande (2009) for example has proposed several revisions to the family Characidae based upon phylogenetic diagnosis. Some genera have been moved to a new subfamily, while others are now (temporarily) assigned to a specific clade within the family pending further study. The recognition of groups of species [clades] within Hyphessobrycon is based primarily on similarities of color patterns; an hypothesis of its intra-relationships is currently unavailable, except for the rosy tetra clade proposed as monophyletic by Weitzman & Palmer (1997).

Hyphessobrycon has until recently been differentiated from Hemigrammus solely on the basis of the fish in Hemigrammus possessing a scaled caudal fin; this however is now known to be unreliable, since it occurs in intermediate conditions (de Lucina, 2003).
