Aphyosemion Gardeni Gold killifish 3-4cm

Aphyosemion gardneri Gold Killifish (3–4cm) is a stunning, beginner-friendly fish with golden hues and red spots—perfect for peaceful, planted aquariums.

The Aphyosemion gardneri Gold, commonly known as the Gold Killifish, is a popular and brightly colored variety of the Aphyosemion gardneri species. Known for its iridescent golden-yellow body, vivid red speckling, and contrasting blue or orange-tinted fins, this 3–4cm fish is an absolute eye-catcher in any peaceful aquarium. Its bold colors, small size, and calm temperament make it a great choice for both beginner and experienced aquarists.

Native to West Africa, A. gardneri thrives in soft, slightly acidic water, and its hardiness and adaptability make it one of the most widely kept killifish species in the hobby. The “Gold” morph has been selectively bred for its bright coloration and makes a striking centerpiece for nano, species-only, or planted community tanks.

🐟 Tank Mates

Gold Killifish are peaceful but do best with non-aggressive, similarly sized companions or in species-only tanks.

Compatible tank mates include:

• Pygmy Corydoras

• Ember or Chili Rasboras

• Otocinclus

• Peaceful shrimp (optional)

• Small snails like Nerites

Avoid:

• Fin-nippers (e.g., barbs)

• Fast, boisterous fish

• Larger predatory species

Keep males with multiple females or singly to reduce potential chasing behavior.

🍽️ Feeding Habits

These fish are micropredators and love live or frozen foods but also adapt well to quality dry foods.

Best foods include:

• Live/frozen baby brine shrimp, bloodworms, daphnia

• Microworms or grindal worms

• High-quality micro pellets or soft granules

• Finely crushed flakes (as a supplement)

Feed once or twice daily in small amounts. Surface and mid-water feeding is ideal due to their upturned mouths.

🧼 Care and Maintenance

• Weekly water changes (20–25%)

• Keep water stable and clean

• Use a tight-fitting lid—they are excellent jumpers

• Provide cover (plants and hiding places) to reduce stress

• Consider spawning mops or moss if you wish to breed them

Breeding is easy and rewarding—eggs can be collected and hatched separately, or fry can be raised in the main tank with dense plant cover.
