The recognition of groups of species 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). 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. Mirande (2009) for example has proposed several revisions to the family Characidae based upon phylogenetic diagnosis. (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.Īuthors 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. It was formerly considered within the subfamily Tetragonopterinae, but Javonillo et.al. The classification is deemed incertae sedis. Durbin in 1908 and presently contains more than 100 described species. The genus Hyphessobrycon-the name from the Greek hyphesson and brycon -was erected by C.H. Some authors suggest the species may cross-breed. The several species in the rosy tetra clade will interact and group together in the aquarium, and remain in the lower half of the water column. On the subject species, the black dorsal fin blotch is sometimes pale, as in the first photo of the pair on the left the right photo is of a female showing the usual darker dorsal distally edged with white.
#RED PHANTOM TETRA PATCH#
The two phantom species share several external traits with the 30 other species in the rosy tetra clade of Hyphessobrycon, including the "signal" black dorsal and a dark shoulder patch immediately behind the gill cover. This species and the closely-related Black Phantom Tetra were originally described in the genus Megalamphodus on the basis of dentition this was determined to be in error and the species were assigned to Hyphessobrycon when the genus Megalamphodus was disbanded by Weitzman & Palmer in 1997. They are egg scatterers and will need soft acidic water in order to spawn. Males have a longer dorsal fin in comparison to the females and are slimmer in body shape in the accompanying photo, the male fish is in front of the female. It should always be kept in a group, minimum six but preferably 8 or more. This species is less tolerant of varying water parameters than its cousin the Black Phantom Tetra. Floating plants will further reduce the light. They do not share the aggressive/bullying tactics of the serpae tetra.Ī tank furnished with a dark substrate, plenty of plants, subdued lighting and leaf litter with peat filtration makes a suitable environment for them. Red phantom tetras are easily distinguished by their lack of white edges on their fins and the prominent black shoulder patch. bentosi, and is closely related to the black phantom tetra ( H. The red phantom tetra bears a similar colouration and shape to several species in the genus Hyphessobrycon such as serpae tetra ( H. Occurs in sluggish tributaries in forested areas, typically blackwater. Soft (hardness to 12 dGH, preferably less) acidic (pH below 7.0) water, temperature 20-23C/68-73F.
Will appreciate daphnia, tubifex worms, earthworms, mosquito larva, mysis shrimps, etc. Accepts standard prepared and frozen foods. Does not fare well in warmer aquaria.Ĭarnivorous. Origin and Habitat: South America: upper Rio Orinoco basin, Rio Muco, Rio Meta, in Columbia.Ĭompatibility/Temperament: Peaceful community fish, suitable companion for similar fish (Neon tetra, Corydoras, etc) that require slightly cooler temperatures than the average community aquarium.
