Geophagus Red Head Tapajos (Geophagus pyrocephalus) — Complete Care Guide
The Geophagus Red Head Tapajos (Geophagus pyrocephalus) is one of the most coveted eartheater cichlids in the hobby. Named for the Rio Tapajos in Brazil, this species is prized for the brilliant red-orange coloration that blazes across its head and upper body, contrasting beautifully with iridescent blue-green flanks. It is a rare find in the trade, making it a true prize for serious cichlid enthusiasts.

Tank Size & Setup
Geophagus are eartheaters — they sift through substrate constantly in search of food. This behavior is central to their care requirements. A minimum of 75 gallons is recommended, with 100+ gallons ideal for a group.
The most important element of their setup is the substrate:
- Fine sand is essential — they must be able to sift it through their gills. Coarse gravel can injure their gill rakers.
- Driftwood and smooth rocks for structure and territory
- Hardy plants like Amazon swords, Vallisneria, or Java fern (they may uproot plants while sifting)
- Moderate flow and excellent filtration — sifting stirs up detritus, so a powerful canister filter is a must
- Dim to moderate lighting
Water Parameters
The Rio Tapajos is a clearwater river with warm, soft, slightly acidic water. Replicating these conditions is key to keeping this species healthy and colorful:
- Temperature: 78–86°F (26–30°C)
- pH: 5.5–7.0 (soft, acidic water preferred)
- Hardness: 1–10 dGH
- Ammonia/Nitrite: 0 ppm
- Nitrate: <15 ppm
Perform 30–40% water changes weekly. This species is sensitive to nitrate accumulation, which can cause stress and color loss. RO water blended with tap water is ideal for achieving the right parameters.
Diet & Feeding
In the wild, Geophagus sift sand to extract invertebrates, organic matter, and small organisms. In the aquarium, replicate this with a varied, fine-particle diet:
- High-quality sinking cichlid micro-pellets or granules as a staple
- Frozen or live foods: bloodworms, daphnia, brine shrimp, blackworms
- Spirulina-based foods for plant-based nutrition
- Avoid large pellets that they cannot sift naturally
Feed 2–3 times daily in small amounts. Scatter food across the substrate to encourage natural sifting behavior.
Temperament & Behavior
Geophagus Red Head Tapajos are generally peaceful cichlids that do best in groups of 5 or more. They establish loose social hierarchies but rarely cause serious injury to tankmates. They are mouthbrooders — females (and sometimes males) will hold fertilized eggs and fry in their mouths for protection. During breeding, pairs may become more territorial but are rarely dangerous to other fish.
Compatible Tankmates
Their peaceful nature makes them excellent community fish for large South American biotope setups:
- Tiger Silver Dollars and other large characins
- Severum cichlids
- Other Geophagus species
- Large peaceful tetras (Bleeding Heart, Congo)
- Large plecos and armored catfish
- Corydoras (in very large tanks)
Avoid aggressive cichlids, fish small enough to be eaten, and species that require very different water parameters.
Breeding
Geophagus pyrocephalus are biparental mouthbrooders. After spawning on a flat surface, both parents may take turns holding the eggs and fry in their mouths. To encourage breeding:
- Keep a group of 5–6 and allow natural pair formation
- Maintain warm, soft, acidic water
- Feed a high-protein diet in the weeks before spawning
- Provide flat rocks or smooth substrate areas as spawning sites
Common Health Issues
- Hole-in-the-head (HITH): Linked to poor water quality and nutritional deficiencies. Maintain pristine water and a varied diet.
- Ich: Treat promptly. This species can be sensitive to some medications — use half doses and monitor carefully.
- Gill damage: Caused by coarse substrate. Always use fine sand.
