Natural habitat

The Peacock Gudgeon inhabits shallow bodies of water in Papua New Guinea, New Zealand, and Australia. They are typically found in still ponds or very slow-moving streams filled with vegetation, thriving in warm waters.

Where they are found

The species is endemic to Papua New Guinea, often found in groups near the substrate of their native habitat.

Aquarium care

Peacock Gudgeons require a well-maintained aquarium with a minimum size of 15 gallons for a pair and more for larger groups. Regular water changes and efficient filtration are essential to keep water quality optimal, as this species is sensitive to ammonia and nitrite spikes. Aquascaping should include dark substrates, rocks, driftwood, and live plants to create a natural habitat.

Feeding

A diet consisting mostly of high-quality dried foods along with live or frozen snacks like brine shrimp, bloodworms, and daphnia is ideal for maintaining health and vibrancy in Peacock Gudgeons. They generally prefer protein-rich live foods.

Compatibility

Peacock Gudgeons are extremely peaceful and can coexist with other similar temperament species. Ideal tank mates include nano fish like Celestial Pearl Danios and Neon Blue Danios, while larger aggressive species should be avoided. They can live harmoniously even in community setups as long as water conditions are properly managed.

Breeding

Breeding peacock gudgeons is relatively straightforward; they need a breeding tank with plenty of hiding spots. The male displays courtship behaviors to attract the female, and after spawning, the male guards the eggs until they hatch after about 8-10 days.
