Bahia Red
Geophagus sp. Bahia Red
The Bahia Red is a beautiful, earth-eating cichlid belonging to the Geophagus brasiliensis complex. They are highly sought after for their vivid red/orange hues and pearlescent spangling. Like all 'eartheaters', they require a fine sand substrate to exhibit their natural sifting behaviors. While generally peaceful for a cichlid, they become aggressively territorial during breeding.

Bahia Red Care Guide Summary
The Bahia Red, scientifically known as Geophagus sp. Bahia Red, 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 semi-aggressive, this species primarily occupies the bottom and mid-level zones of the aquarium and produces a high level of biological waste.
To thrive, the Bahia Red requires a freshwater only aquarium with a minimum volume of 250 litres and a tank length of at least 120 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 6–7.5 and a general hardness of 4–15 dGH. A moderate water flow is preferred.
The Bahia Red is a rewarding species to keep, provided its core environmental needs are met. This species is available in 3 varieties: Male, Female, and Juvenile. 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.
Bahia Red Habitat Setup
When setting up an aquarium for the Bahia Red, a moderate water flow best suits their natural preferences. Because this species occupies the bottom and mid-level zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and driftwood, which can serve as both a hiding place and a dietary supplement. Keepers should note that expect substrate disturbance, so lightweight décor should be secured and live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation.
Bahia Red Compatibility Notes
Classified as semi-aggressive, the Bahia Red is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, territorial behaviour may cause issues if hiding spots or floor space are limited and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the bottom and mid-level zones can help reduce competition and territorial overlap.
Who Bahia Red Is Actually For
Bahia Red is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.
The most common mistake is treating Bahia Red like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

Is Bahia Red peaceful or aggressive?
Bahia Red is classified as semi-aggressive with an aggression score of 5 out of 10. They can work in community setups but may clash with certain tankmates.
Can Bahia Red live alone?
Yes, Bahia Red can be kept singly or in a group. They are flexible and adapt well to both setups.
Does Bahia Red have any special tank requirements?
Yes. Bahia Red benefits from sand (sifters) and driftwood (digestion/hiding) in the aquarium. These features help replicate their natural habitat and promote overall health and well-being.

Fish Similar to Bahia Red
Red Striped Eartheater
Geophagus surinamensis
A large, relatively peaceful South American cichlid famous for its 'earth-eating' behavior. They constantly sift fine sand through their gills to forage for benthic invertebrates. A soft sand substrate is absolutely mandatory for their long-term health to prevent gill damage and stress. While gregarious and best kept in groups, they establish a strict pecking order.
Red Hump Eartheater
Geophagus steindachneri
A fascinating South American cichlid famous for its constant sand-sifting behavior to find food. They are maternal mouthbrooders. Unlike many large cichlids, they are relatively peaceful toward other species, making them excellent candidates for large community tanks, though conspecific males will clash.
Red Head Tapajos (Geophagus)
Geophagus sp. 'Red Head Tapajos'
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.
Uruguayan Eartheater
Gymnogeophagus australis
A beautiful, subtropical eartheating cichlid from the Uruguay River basin. They constantly sift sand for food and are generally peaceful but territorial during breeding. Crucially, they require a cool 'winter' period (15-20°C) to thrive long-term; keeping them at year-round tropical temperatures will drastically shorten their lifespan and cause them to lose color.
Pearl Eartheater
Geophagus brasiliensis
A robust, highly adaptable South American cichlid known for its iridescent pearl-like spangling. While classified as an 'eartheater' (sifting sand for food), they are less obligate sifters than other Geophagus species but still require a soft sand substrate. They are surprisingly tolerant of cooler water and even brackish conditions. They are aggressive for eartheaters, especially when breeding.
Geophagus Orange Head Tapajos
Geophagus sp. 'Orange Head'
A stunning and relatively peaceful South American 'eartheater' native to the Rio Tapajós. They are famous for the vibrant orange/red coloration on the heads of mature adults and their fascinating feeding behavior. They are gregarious and must be kept in groups. Fine sand substrate is absolutely mandatory, as they constantly sift it through their gills to forage.
