Habitat

Gold Emperor Tetras occur naturally in the slow-moving rivers and streams of Colombia. They prefer to live in densely planted regions with abundant hiding places. They like soft, slightly acidic water and prefer a dimly lit tank with driftwood and leaf litter.

In an aquarium, you must provide a condition similar to their natural environment. Planting live plants such as Java Fern, Anubias, and Hornwort will make them at ease.

Gold Emperor Tetra Diet

Gold Emperor Tetras are omnivores and consume plant and protein foods. Their diet must consist of:

• High-quality flake or pellet food (daily nutrition)
• Live or frozen foods (e.g., bloodworms, brine shrimp, and daphnia)
• Vegetables (such as spinach, zucchini, and peas)
• Algae-based foods (for digestive support)

Feed them in small amounts twice a day to maintain their health and avoid overfeeding.

Social Behavior  

Gold Emperor Tetras are peaceful and social fish. They are most contented when maintained in groups of at least 6 or more. Keeping them singly will lead to stress and dull coloration.

These fish are friendly and docile. They are not very aggressive but may form a pecking order within their school.

• Neon Tetras
• Guppies

Bad Tank Mates  

Do not keep them with aggressive or fin-nipping fish. Poor tank mates include:

Gold Emperor Tetra Breeding

Gold Emperor Tetras are easy to breed but need special care. Follow these steps:

Create a different breeding tank with soft acidic water.

Add fine-leaved plants or a spawning mop for eggs to be laid on.

Release a well-fed male and female pair.

Feed fry on infusoria or baby brine shrimp.
