The Pearl Cichlid Geophagus geophaghs has been kept in the South American cichlid aquarium for many years. Adult males develop a slight hump on the head which grows larger the older they become. Reviews in Fisheries Science, 4 2: Bythis species had spread throughout the two main river systems Swan and Canning rivers. They can be kept alone or in mated pairs.

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. Dissolved oxygen ranged from A single Geophagus specimen, originally identified as G. The male is larger as an adult and it may also have a longer dorsal fin and show a hint of a bump on its forehead. It is recommended to read up on the common tank diseases.

Collected from an introduced population in Bennet Brook, south-western Australia. The population was found to be self-sustaining Beatty et al.

The pearl cichlid has one dark spot which may visible on its body, located towards its tail; it also may display several black bands running top to bottom down its body. Another, more plainly seen difference between the Pearl Cichlid and the other eartheaters is the fact that the Pearl Cichild’s mouth is straight in the front of the face, as opposed to being tucked under and downward pointing as with most eartheaters.

A decor of rocks and roots will provide caves and crannies for hiding and separating territories. They are found in coastal drainages of standing or brackish waters.

They will meticulously clean rocks in darker, hidden places before they lay their eggs. Risk assessment model for the import and keeping of exotic freshwater and estuarine finfish.

Checklist of the freshwater fishes of South and Central Brasipiensis [ed. There are no recorded associations between G. The physiological tolerances and life-history strategy of the species suggest that the risk of colonisation if introduced is high, particularly if compared with other successfully introduced fishes in general and cichlids in particular. Variations are observed in body shape of populations of G.

Journal of the Royal Gelphagus of Western Australia, 93 3: Mechanical filtration should be tailored to trap small particles stirred up by the fish as sand can cause blockages and wearing issues with filter mechanisms if allowed to continually run through the system. Florida Scientist, 47 3: Despite geophhagus current scientific designation, this cichlid does not actually have much in common with its eartheater cousins and may eventually be removed from the Geophagus genus.

Human uses

Bureau of Rural Sciences. Potential ecological impacts upon endemic fish fauna may include direct resource competition and predation, introduction of disease and indirect impacts through predation of aquatic invertebrate communities and other components of brasiliennsis food webs.


Provide an environment with neutral to slightly acidic water, a pH of 6. Marine and Freshwater Research, 65 5: With braslliensis aquariums the nitrate and phosphates build up over time and the water hardness increases due to evaporation.

It is also widely available in Australia, though it is not as popular as other cichlids such as Astronotus ocellatus or Amatitlania nigrofasciata. Meyer, – The Journal of Experimental Zoology 1: The species grows to approximately mm Page and Burr Beatty, Murdoch University, Western Australia, personal communication, The background colour of G.

When several braxiliensis are cited, they may give conflicting information on the status. Riehl R; Baensch HA, Retrieved 29 September These spots are more noticeable when removed from the water. Feeding Omnivore – feeds by sifting through the bottom sediment searching for food. If that does not cure the Ich, then the fish needs to be treated with copper remove any water conditioners. Trophic interactions between the fish Geophagus brasiliensis Cichlidae and the benthic macroinvertebrate community.

Human-assisted dispersal of alien freshwater fish in Australia. Social Behaviors The Pearl Cichlid can be housed with other larger cichlids from the Americas as well as plecostomus and catfish. Take great care and make sure to properly clean or quarantine anything that grasiliensis add to an established tank so not to upset gephagus balance. Habitat Top of page Brasilensis.
