Peacock Gudgeons are native to the tropical freshwaters of Oceania. Found primarily in Papua New Guinea, they inhabit environments that mirror calm, peaceful environments. They’re also found in parts of Australia and New Zealand, indicating a preference for the Pacific region’s warm, gentle waters.
Peacock Gudgeons thrive in shallow waterbodies in these locations. They’re often sighted in still ponds or slow-moving streams, unlikely to venture into fast-moving currents. The tranquility of these waters is crucial for their livelihood, offering stability for their vibrant ecosystem. They also thrive in areas with abundant vegetation, serving as both their sanctuary and breeding grounds.
Peacock Gudgeon Appearance and Physical Characteristics
Peacock Gudgeons present a distinctive physique characterized by an elongated body and a rounded head. Adult males can be identified by a nuchal hump, which accentuates their rounded profile. The skin of these fish emits a bluish-silvery sheen, enhanced by a tapestry of pink, black, and yellow markings. Their fins are notable, bordered with thick, vivid yellow edges.
The sexual dimorphism in Peacock Gudgeons is prominent, helping in their identification. Males generally reach lengths up to 3 inches (7.6 centimeters) and express a bright color palette and potentially a prominent nuchal hump. In contrast, females are smaller growing up to a maximum of 2 inches (5.1 centimeters). They display a black edge on their anal fin and a distinguishing yellow belly, unique to their gender.
Peacock Gudgeons have vertical red dotted stripes on their body and a yellow abdomen when seen from the side. The distinctive black spot located at the base of each caudal fin is a defining characteristic of these fish, which is why they’re often referred to as ‘Peacocks’.
Behavioral Characteristics of Peacock Gudgeon
Peacock Gudgeons, scientifically named Tateurndina ocellicauda, show distinct behaviors that reflect their peaceful and nonaggressive nature. Males are particularly vibrant in color and engage in unique courtship rituals to woo potential mates. These displays of fin flaring and elaborate dances aren’t just mesmerizing but are key indicators of their readiness to breed.
Male Peacock Gudgeons are highly territorial, particularly during the breeding season. They choose and defend specific areas within the aquarium, which often include the most favorable spots for female attraction. It’s vital to understand their need for space since this territorial aggression is an inherent aspect of their natural breeding behavior.
Peacock Gudgeons often form shoals in their native habitat of slow-moving freshwater streams and rivers with plenty of vegetation. These group structures suggest their social behavior and preference for companionship, which makes them suitable for community aquarium settings.
Peacock Gudgeon Diet and Lifespan
Peacock Gudgeons thrive on a diverse diet. They primarily feed on water fleas, insects, insect larvae, worms, and other tiny crustaceans in their natural diet.
In captivity, you can feed them a mix of live and frozen food for optimal growth. Live or frozen bloodworms, daphnia, and brine shrimp are all great food sources. Some aquarists have found success with high-quality dried food, but Peacock Gudgeons typically prefer live or frozen snacks.
Peacock Gudgeons can live for 3 to 5 years in captivity under proper care. To maximize their longevity, attention to water quality and proper diet is essential. Moreover, genetics play a role in their lifespan, a factor to consider when sourcing fish.

How to Set up An Aquarium for Peacock Gudgeon?
When setting up an aquarium for Peacock Gudgeons, mimic their natural habitat for their wellbeing. Begin by selecting a tank that is at least 10 gallons, providing ample space for swimming and territory establishment. Equip your tank with a filtration system; opt for one with an adjustable flow rate to ensure the low water current that these fish need.
The next step is to focus on water parameters that are vital for the health of your fish. Maintain water pH levels between 6.5 to 7.5, and adjust water hardness based on their preference for slightly acidic conditions. Regular water testing kits will be indispensable in monitoring these parameters.
To create a suitable environment, arrange a soft sandy substrate along with rocks, driftwood, and an abundance of live plants. These elements not only replicate the Peacock Gudgeons’ natural setting but also provide hiding spots that are crucial for their sense of security.
Water temperature should be kept consistent, ranging between 72°F to 79°F (22.2°C to 26.1°C). Install a reliable heater and check the temperature daily with a quality aquarium thermometer to prevent any harmful fluctuations.
The water flow should be minimal since Peacock Gudgeons aren’t adept swimmers. Position the water output to target the tank’s glass, thereby diffusing the current. This setup ensures that the fish don’t struggle against the water movement and can swim freely.
Incorporate a lighting system that mimics natural daylight cycles. Moderate lighting that enhances plant growth while allowing the Peacock Gudgeons to display their vibrant colors is ideal.
Regular maintenance includes water changes and filter cleaning, helping to keep the tank environment stable and toxin-free.
Ideal Tank Mates for Peacock Gudgeon
When selecting tank mates for your Peacock Gudgeons, consider their peaceful nature and tendency toward non-aggressive predation. These fish view very small fish as potential food but can coexist with a variety of other species harmoniously.
Freshwater shrimps like adult Red Cherry and Ghost Shrimp make safe companions due to their larger size. Similarly, freshwater Snails such as Nerite Snails are excellent choices, given that they aren’t at risk of predation.
New Guinea and Australian Rainbowfish are other compatible tank mates since they both inhabit the same region. Incorporating plants like Indian Fern or Philodendron can enhance this naturalistic setting.
Carefully consider the size and temperament of any fish you introduce to the Peacock Gudgeon’s space. Larger territorial fish are unsuitable if the tank does not provide ample room for all occupants. A spacious aquarium coupled with abundant hiding spaces ensures a safe and balanced atmosphere for all. To achieve this, consider the following tank mates known for their compatibility:
- Cherry Barb,
- Celestial Pearl Danio,
- Harlequin Rasbora,
- Neon Tetra,
- Corydoras Catfish,
- Dwarf Gourami, and
These species tend to be peaceful schoolers, which can add movement and life to your aquarium without inciting stress or conflict amongst its inhabitants.
How to Breed Peacock Gudgeon?
Breeding Peacock Gudgeon needs observation of their unique courtship process. Males engage in a mating dance to captivate females. If a female is impressed by the display, she follows the male to his nesting site.
Proper tank conditions significantly impact breeding success. Tanks should mirror the shallow, vegetation-rich waters of their native habitat. Ensure that water temperatures range between 72°F to 79°F (22.2°C to 26.1°C). A pH level of 6.5 to 7.5 is ideal for promoting successful breeding.
Initiate breeding by feeding high-quality foods. Live or frozen foods, such as bloodworms and brine shrimp, trigger the breeding cycle. Offer these in conjunction with a balanced diet to ensure that the pair is in prime health.
Focus on the substrate when preparing for egg laying. Males create bubble nests on the tank bottom. A sandy or fine gravel substrate facilitates this nesting behavior. Maintaining cleanliness is crucial. Rinse the substrate thoroughly to prevent harmful substances from impacting the eggs.
When the female lays eggs, the male is responsible for their care. He guards the nest and ensures a steady flow of oxygenated water by fanning his fins.
Monitor the water parameters diligently during the breeding period. Stability in water quality helps in the development of eggs and the growth of fry. Engage in regular tank maintenance and partial water changes to preserve optimal conditions without disturbing the nest.
With attention to diet, water conditions, and appropriate substrate, aquarists can successfully rear these vibrant fish.
