Geophagus sp. Bahia Red

Cichlids - South American
Reviewed by Guidarium Editorial DeskUpdated April 29, 2026

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 Varieties

Each variety inherits the species defaults above. Only differences are highlighted.

Male

Males grow significantly larger, exhibit brighter red/orange coloration, develop longer fin trailers, and may grow a small nuchal hump as they mature.

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 67.5 and a general hardness of 415 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.

Fish Similar to Bahia Red

Red Striped Eartheater

Geophagus surinamensis

Cichlids - South American
25 cm Mostly Peaceful

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

Cichlids - South American
15 cm Semi-Aggressive

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'

Cichlids - South American
18 cm Mostly Peaceful

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

Cichlids - South American
14 cm Semi-Aggressive

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

Cichlids - South American
25 cm Semi-Aggressive

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'

Cichlids - South American
18 cm Mostly Peaceful

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.
