Distribution

Known only from minor jungle tributaries, presumably of the Solimões river's north bank, close to the city of Leticia, Amazonas department, Colombia. The city …

Habitat

No firm details are available but the closely-related A. barlowi is collected from small forest streams where it shows a preference for clear, relatively cool,…

Aquarium size

Base dimensions of 60 ∗ 30 cm24 ∗ 12 in or more are just about acceptable for a single pair, though this species seems to fare better in larger aquaria.

Maintenance

Provided adequate cover and structure is available this species is unfussy with regards to décor with ceramic flowerpots, lengths of plastic piping and other a…

Diet

Seems to be primarily carnivorous and likely to feed mostly on benthic invertebrates in nature. In the aquarium live and frozen foods such as Artemia, Daphnia …

Behaviour and compatibility

Best maintained alone or with small 'dither' fishes such as Nannostomus spp., and ideally should not be mixed with other Apistogramma. Relative to some other m…

Sexual dimorphism

Males are larger, more colourful and develop more extended fins than females.

Reproduction

Facultative, biparental, larviphorous mouthbrooder. A. barlowi is the only other member of the genus known to employ such behaviour which is also remarkable fo…

This undescribed species was first collected and subsequently appeared in the aquarium hobby during 2008. It was exported again in late 2009 and early 2010 under the names A. sp. 'Jutai' and A. sp. 'diamond face', and said to have been collected in the Río Jutai, Amazonas state, Brazil. The Jutai is a south bank tributary of the Solimões but lies several hundred kilometres downstream of Leticia so this information, from a purportedly trustworthy source, initially caused confusion. The exporter later let it be known that the fish were in fact collected near Leticia and they appear conspecific with the fish from 2008. It's also appeared on trade lists as A. sp. 'Leticia'. 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, complexes and groups by authors in order to better separate them. Such lists have been augmented by fish that have appeared in the aquarium trade and are in a state of near-constant flux. For example the A. barlowi complex, of which A. sp. 'Kelleri' is a member, is contained within the A. atahualpa group within the larger A. trifasciata lineage. Kullander (1998) conducted a morphology-based phylogenetic study in which the neotropical family Cichlidae was divided into six subfamilies of which the putative subfamily Geophaginae contained 16 genera divided among three 'tribes': Acarichthyini - Acarichthys and Guianacara. Crenicaratini - Biotoecus, Crenicara, Dicrossus and Mazarunia. Geophagini - Geophagus, Mikrogeophagus, 'Geophagus' brasiliensis group, 'Geophagus' steindachneri group, Gymnogeophagus, Satanoperca, Biotodoma, Apistogramma, Apistogrammoides and Taeniacara. Later molecular studies by Farias et al. (1999, 2000, 2001) resulted in the additions of Crenicichla and Teleocichla to the Geophaginae, a result supported by López-Fernández et al. (2005) who conducted the most detailed molecular analysis of the grouping to date including 16 of the 18 genera and 30 species. However their conclusions regarding interrelationships between genera did vary somewhat from previous hypotheses and can be summarised by the following loosely-defined groups: - a weakly-supported sister group relationship between Acarichthys and Guianacara. - a well-supported "Satanoperca clade" comprising Satanoperca, Apistogramma, Apistogrammoides and Taeniacara. - a "big clade" with Geophagus, Mikrogeophagus, 'Geophagus' brasiliensis group, 'Geophagus' steindachneri group, Gymnogeophagus, Biotodoma, Crenicara and Dicrossus. - a "crenicarine clade" with Biotoecus and Crenicichla. No representatives of Teleocichla or Mazarunia were included in the study but the former is well-established as sister to Crenicichla while the latter has grouped closely with Dicrossus and Crenicara in earlier works. The other main conclusions of the paper are confirmation that Geophaginae is a monophyletic group exhibiting strong signs of having undergone rapid adaptive radiation (diversification of a species or single ancestral type into several forms that are each adaptively specialised to a specific environmental niche).

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the profileFor example, the Behaviour and compatibility section already says this.
