Gold Ram (Mikrogeophagus ramirezi)

Gold Ram

Scientific name: Mikrogeophagus ramirezi (gold color morph)
Other names: Golden Ram, Gold German Blue Ram

Quick Overview

• Family: Cichlidae
• Adult size: 5–7 cm (2–2.75 in)
• Lifespan: 2–4 years (often shorter with poor water quality)
• Temperament: Peaceful but territorial when breeding
• Difficulty: Moderate (water quality sensitive)

What Is a Gold Ram?

The Gold Ram is a selectively bred color morph of the German Blue Ram. Through line breeding, the blue pigmentation is reduced, resulting in a gold/yellow body, red eyes, and variable black markings. Care requirements are identical to standard rams, and they are not albino despite the lighter coloration.

Appearance & Identification

• Golden yellow to cream body with subtle iridescence
• Red or pink eyes
• Dark central body spot (may be faint or absent in some specimens)
• Long dorsal fin rays in males
• Males: slimmer, extended dorsal rays
• Females: shorter fins, often a pinkish belly when mature

Natural Origin (Species Background)

• Wild form native to the Orinoco River basin (Venezuela, Colombia)
• Naturally inhabits:
  • Warm, slow-moving waters
  • Sandy bottoms
  • Soft, acidic conditions
• Captive strains are far less tolerant of poor conditions than wild fish

Aquarium Care

Tank Size & Setup

• Minimum tank: 20 gallons (30+ ideal for pairs or community tanks)
• Best environment includes:
  • Fine sand substrate
  • Smooth stones
  • Driftwood
  • Dense plants with open foreground
  • Calm flow (avoid strong current)

Rams spend much of their time near the bottom and mid-water.

Water Parameters (Critical)

Gold Rams are very sensitive, especially store-bought imports.

• Temperature: 27–30 °C (80–86 °F) ✅ most important factor
• pH: 5.5–7.0 (stable is more important than exact number)
• Hardness: 1–6 dGH (soft water strongly preferred)
• Ammonia/Nitrite: 0
• Nitrate: <10 ppm ideal

⚠️ Cooler water or unstable parameters often cause:

• Loss of color
• Weak immune response
• Early death (the #1 cause of failure with rams)

Behavior & Compatibility

• Generally peaceful
• Males become territorial during breeding
• Can be kept:
  • Singly
  • As a bonded pair
  • In small harems (1 male, 2 females in larger tanks)

Good Tankmates

• Small tetras (cardinal, rummynose)
• Corydoras (heat‑tolerant species)
• Otocinclus
• Pencilfish
• Peaceful dwarf cichlids (space permitting)

Avoid

• Fin nippers
• Aggressive cichlids
• Cool‑water species
• Boisterous bottom dwellers

Diet

Omnivorous but prefers protein-rich food.

Staple diet:

• High-quality micro pellets or fine flakes

Enhancements:

• Frozen: bloodworms, brine shrimp, mysis
• Live foods greatly improve color and breeding condition

Feed 1–2× daily in small amounts.

Breeding Notes

• Open substrate spawners
• Lay eggs on flat stones or leaves
• Parents may guard eggs—but domestic strains often abandon or eat eggs
• Fry require:
  • Very clean water
  • Infusoria or powdered fry foods initially

Breeding success is higher with locally bred stock rather than imports.

Common Issues (Very Important)

• Sudden deaths after purchase → usually temperature or water mismatch
• Thin, sunken bellies → internal parasites
• Clamped fins, lethargy → stress from poor water or low heat

 Slow acclimation and high temperature dramatically increase success.
