Buffalo Head Cichlid (Steatocranus casuarius)

Overview

Common Name: Buffalo Head Cichlid
Scientific Name: Steatocranus casuarius
Region of Origin: Congo River Basin, Africa
Maximum Size: 4–5 inches (10–13 cm)
Minimum Tank Size: 30 gallons
Lifespan: 8–10 years
Care Level: Intermediate
Temperament: Semi-aggressive
Preferred Tank Zone: Bottom
Schooling Behavior: No – prefers to form pairs or small groups

Description:
The Buffalo Head Cichlid is a riverine species admired for its distinct cranial hump, slow-swimming behavior, and intriguing personality. Unlike most African cichlids, it prefers fast-flowing water and will often “hop” along the bottom due to its reduced swim bladder. Best kept in river tank setups with rocks, caves, and plenty of oxygenation.

Water Parameters

  • Temperature: 72–79°F (22–26°C)
  • pH Range: 6.0–7.5
  • Water Hardness (GH): 4–12 dGH
  • Carbonate Hardness (KH): 3–8 dKH
  • Water Type: Freshwater, slightly acidic to neutral

Aquascape Recommendations

  • Strong filtration with current
  • Rounded river rocks and stacked caves
  • Sandy or fine gravel substrate
  • Driftwood for additional cover
  • Hardy plants (optional, as they may dig)

Feeding & Diet

Diet Type: Omnivore

Core Diet

  • High-quality sinking pellets or wafers
  • Algae-based granules
  • Spirulina flakes

Supplements & Treats

  • Live or frozen bloodworms
  • Brine shrimp
  • Mysis shrimp

Feeding Notes:
Due to their bottom-dwelling nature, feed sinking foods and ensure they reach the substrate. Avoid excessive high-protein foods to reduce waste buildup.

Behavior & Compatibility

  • Temperament: Semi-aggressive; territorial toward conspecifics
  • Best Tank Mates: Peaceful riverine species, small barbs, Congo tetras
  • Avoid Housing With: Hyperactive or large aggressive species
  • Territorial Behavior: Highly territorial during spawning
  • Behavior Type: Cave dweller, bottom-hopper
  • Activity Level: Sedentary but alert; prefers low water column movement

Breeding

  • Breeding Method: Substrate spawner
  • Breeding Setup: Rocky caves or clay tubes for egg-laying
  • Spawning Behavior: Pair bonds form; female guards eggs inside cave
  • Fry Care: Male defends territory; fry become free-swimming in ~7 days
  • Note: Moderate difficulty — best in species-only tanks when breeding
