A stunning and relatively peaceful South American Eartheater, recently formally described as Geophagus pyrocephalus. They are named for the bright red/orange coloration that develops on the heads of mature adults. As 'eartheaters', they constantly sift substrate through their gills to find food, making fine sand an absolute requirement to prevent injury. They are social cichlids that must be kept in groups.

Available Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Standard (Adult)
Adult specimens displaying the characteristic bright red head (more prominent in dominant males). Best kept in groups of 5+ to diffuse mild conspecific bickering and encourage natural shoaling behavior.
Differs in 1 trait from base species
Also known as: Adult, Breeding Size
Juvenile (Grow-out)
Juveniles are typically silver/grey and lack the distinctive red head, which develops as they mature. They can be grown out in slightly smaller tanks temporarily but will grow quickly.
Differs in 6 traits from base species

Red Head Tapajos (Geophagus) Care Summary
The Red Head Tapajos (Geophagus), scientifically known as Geophagus sp. 'Red Head Tapajos', belongs to the Cichlids - South American family group. Adults reach a maximum size of approximately 18 cm and have a compressed body shape with a moderate growth rate. Classified as mostly peaceful, this species primarily occupies the bottom and mid-level zones of the aquarium and produces a high level of biological waste.
To thrive, the Red Head Tapajos (Geophagus) requires a freshwater only aquarium with a minimum volume of 280 litres and a tank length of at least 120 cm. Water temperature should be maintained between 26°C and 30°C, with a pH range of 5.5–7.5 and a general hardness of 1–10 dGH. A moderate water flow is preferred. To replicate their natural habitat, the tank should include sand (sifters), smooth gravel (sensitive barbels), and driftwood (digestion/hiding).
This species should be kept in groups of at least 5 to reduce stress and encourage natural behaviour. Keepers should be aware that this species will defend a territory within the tank and may uproot or eat live plants. This species is available in 2 varieties: Standard (Adult) and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Similar Species
Firemouth Cichlid
Thorichthys meeki
A popular Central American cichlid famous for the bright red coloration on its throat and belly, which it flares to intimidate rivals. They are earth-eaters, constantly sifting sand for food. While territorial, especially during breeding, they are relatively peaceful for a cichlid of their size compared to larger Central American counterparts.
Dwarf Gourami
Trichogaster lalius
A peaceful to semi-aggressive labyrinth fish native to South Asia. Famous for their brilliant metallic blue and red stripes. While generally suitable for community tanks, males are territorial toward each other and similar-looking fish. They are sensitive to water quality and prone to Iridovirus if stressed. Requires access to the surface to breathe.
Red Rainbowfish
Glossolepis incisus
Native to Lake Sentani in Indonesia, this species is famous for the brilliant salmon-red coloration of mature males. They are large, active schooling fish that develop a distinct high-arched back as they age. Females are vastly different in appearance (olive-gold). They require hard, alkaline water and plenty of swimming space.
Clown Killifish
Epiplatys annulatus
A striking nano killifish resembling a tiny rocket. Native to West African swamps, they have distinct black and yellow vertical bands. They are strictly surface dwellers (top-level) and are non-annual, meaning they live longer than annual killifish (2-3+ years). They are notorious jumpers and require a tight lid.
African Jewel Cichlid
Hemichromis bimaculatus
A strikingly beautiful but notoriously aggressive West African riverine cichlid. Unlike the alkaline-loving Rift Lake cichlids (e.g., Mbuna), Jewel Cichlids prefer neutral, softer water parameters. They are renowned for their brilliant red breeding dress and iridescent blue spots, but also for their extreme territoriality, especially when forming pairs and spawning. They are avid diggers and will uproot most plants.
Platy
Xiphophorus maculatus
A quintessential community fish known for its durability and massive variety of colors. Native to Central America, Platies are livebearers, meaning they give birth to free-swimming fry. They are peaceful, active grazers that require hard, alkaline water to thrive. They are excellent for beginners but breed prolifically.
