Apistogramma hoignei MEINKEN, 1965

March 13th, 2012 — 1:22pm

The genus Apistogramma is among the most speciose of South American cichlid genera with around 70 species valid at present but many more awaiting description. In addition many species exist in two or more geographical colour forms which may or may not turn out to be distinct in the future. Hobbyists tend to label these with collection data if available in order to avoid mixing them and the potential of hybridisation.

Member species have also been organised into a series of species lineages, sublineages, complexes and groups by authors in order to better separate them.

Aequidens tetramerus (HECKEL, 1840)

Saddle Cichlid

March 13th, 2012 — 1:21pm

This is the type species of the genus Aequidens and has the widest distribution of any member species. It exists in various colour forms depending on locality with variants from Ecuador and Peru being particularly sought after since they develop striking red (Ecuador) or orange (Peru) colouration on the lower part of the jaw, head and anterior portion of the belly whereas those from Brazil tend to have an overall grey/blue/green colouration, for example.

Despite its type status it's long…

Hyphessobrycon sweglesi (GÉRY, 1961)

Red Phantom Tetra

March 13th, 2012 — 1:20pm

At least two colour forms have been traded, one of which is more intensely-coloured and has been referred to as H. sweglesi ‘red’ or ‘rubra’. The bright red pigmentation is retained in long-term captive specimens, suggesting that it is not considered to be an artefact of diet, but we suspect it might reflect conditions at the collection locality with the reddest fish putatively inhabiting blackwater and plainer forms clearwater environments. Zarske (2014) found the two forms to be identical in terms of morphology an…

Anostomus ternetzi FERNÁNDEZ-YÉPEZ, 1949

Ternetz's Anostomus

March 13th, 2012 — 1:19pm

This species is widely-distributed in the Río Orinoco system in Brazil, Colombia and Venezuela plus coastal drainages in Guyana, Suriname and French Guiana including the Essequibo and Mazaruni.

Type locality is ‘Palital, Estado Guárico, Venezuela’ which appears to correspond to a wetland called Esteros de Palital in the Aguaro-Guariquito National Park of Guárico state, northern Venezuela.
