Overview of Thorichthys maculipinnis (Elliot’s Cichlid)

Synonyms:
Cichlasoma ellioti, Heros maculipinnis, Thorichthys ellioti

Distribution:
Native to Mexico, primarily found in the Rio Papaloapan basin.

Size:
Up to 15 cm (5.9 inches).

Temperature:
Optimal range is 24–30°C.

Water Parameters:
Prefers neutral to slightly alkaline conditions.

• pH: 7.5–8.0
• dH: Up to 18°

Compatibility:

• Best suited for community tanks without small or slow-moving fish.
• Relatively peaceful outside of breeding periods.

Lighting:
No specific requirements.

Sexual Dimorphism:

• Females typically have a dark blotch in the dorsal fin, absent in males.
• Males grow larger and both sexes are colorful.

Care

• Habitat: Natural habitats include slow-moving, murky river waters with sandy substrates, driftwood, and minimal vegetation.
• Aquarium Setup:
  • Use fine, soft sand to protect the gills during substrate sifting.
  • Include driftwood, smooth rocks, and optional robust live plants for cover and aesthetics.
  • Ensure a 4–6 ft tank for adequate space and reduced territorial stress.
• Water Quality: Maintain high water quality to avoid health issues caused by nitrates.
• Behavior:
  • Territorial when breeding, but generally peaceful.
  • Can bluff with gill-flaring displays but avoid large aggressive tankmates.
  • Ideal tankmates include Severums, Blue Acaras, and robust livebearers like swordtails. Avoid delicate species like Corydoras.

Feeding

Diet:
Omnivorous but susceptible to digestive issues with excessive protein.

• Recommended Foods:
  • Frozen: Vitamin-enriched brine shrimp, white mosquito larvae, daphnia, and Mysis.
  • Dried: Flake, green flake, granules, cichlid pellets, algae wafers.
  • Fresh vegetables for fiber and variety.

Breeding

• Sexual Maturity: Reached at 6–7 cm.
• Spawning:
  • Occurs on smooth, sheltered surfaces like flat rocks.
  • Females lay 100–500 eggs in batches, fertilized by the male.
  • Eggs hatch within 72 hours, and fry become free-swimming in 3–5 days.
• Parental Care: Both parents guard fry until they reach 1–2 cm.
• Fry Diet: Start with crushed flake, powdered baby food, or baby brine shrimp.

Thorichthys maculipinnis is a colorful, relatively peaceful species suitable for well-planned community setups, thriving in naturalistic environments with ample swimming space and proper care.
