Within this small group G. Representatives of the G. There are currently thirteen described members but diversity is predicted to eventually prove much greater with a number of undescribed forms known some of which, such as G.
Geophagus and a number of related genera are often included in the putative subfamily Geophaginae. Acarichthyini — Acarichthys and Guianacara. Crenicaratini — Biotoecus , Crenicara , Dicrossus and Mazarunia. Later molecular studies by Farias et al. However their conclusions regarding interrelationships between genera did vary somewhat from previous hypotheses and can be summarised by the following loosely-defined groups:.
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.

Geophagus is a genus of cichlids that mainly live in South America as far south as Argentina and Uruguaybut a single species, G.
Though described in it was first collected much earlier and misidentified by Gosse as G. By using argyrosticttus site, you agree to the Terms of Use and Privacy Policy. There are currently 28 recognized species in this genus.
Some cichlids previously included in this genus have been reallocated to BiotodomaGymnogeophagus or Satanoperca. This species is relatively rare in the hobby but sometimes available from specialist retailers or private breeders. A degree of patience is also required since it can be at least a year until they become sexually mature.
Assis, — Zootaxa From Wikipedia, the free encyclopedia. Unlike the majority of congeners which practice mouthbrooding this species is a substrate -spawner adopting a fairly basic strategy. Views Read Edit View history. Here they dig a large pit which may be defended for some geopgagus before a smaller site is selected within it just prior to spawning. Detail of flank patterning.
Anostomus ternetziPseudanos trimaculatusAcnodon normaniHyphessobrycon heterorhabdusH. In other projects Wikimedia Commons Wikispecies. Sexual Dimorphism Juveniles are impossible to sex accurately by external means unless spawning when the ovipositor of the female is clearly visible. Courtship is relatively unobtrusive consisting of fin flaring, circling, gaping and head jerking displays, and when ready to spawn a pair will select a suitable site.
Other fishes are not tolerated in the vicinity of the pit and in smaller aquaria may need to be removed. Like all eartheaters, a substrate of fine sand is essential for their well-being in the aquarium and they will spend most of their time sifting it through their specialized gills to pick out small food particles.
