Peacock Goby, also known as Tateurndina ocellicauda, is a charming freshwater fish native to Papua New Guinea. Known for their vibrant colors and distinctive behaviors, these gobies have gained popularity among aquarium enthusiasts. They are named "peacock" due to the dazzling iridescent blue and green hues reminiscent of peacock feathers that adorn their bodies.

Peacock Gobies have a compact and elongated body shape, with the males being more colorful and slightly larger than the females. Their main attraction lies in their striking coloration, featuring shimmering shades of blue, green, and hints of yellow. These colors intensify during courtship and spawning, making them a captivating sight in the aquarium.

Caring for Peacock Gobies is relatively straightforward, making them suitable for aquarists with varying experience levels. They prefer well-maintained aquariums with stable water conditions. Although adaptable to different water parameters, maintaining good water quality is crucial to their well-being.

Creating a suitable environment for Peacock Gobies involves providing them with plenty of hiding spots created by rocks, caves, and driftwood. A sandy substrate mimicking their natural habitat is preferred, as they enjoy burrowing and sifting through the sand. They also appreciate the presence of plants, which not only add to the aesthetic but also provide additional hiding places.

Peacock Gobies are peaceful by nature and can be kept in a community aquarium with other small, non-aggressive fish species. Due to their relatively small size, it's important to avoid housing them with larger, aggressive tank mates that may pose a threat.

Their diet mainly consists of small live and frozen foods. In the wild, they feed on tiny aquatic insects and crustaceans. In the aquarium, they can be offered a variety of foods, including high-quality flakes, small pellets, and live or frozen treats such as brine shrimp, bloodworms, and daphnia. Providing a balanced diet will help maintain their health and vibrant colors.

Breeding Peacock Gobies in a home aquarium can be challenging due to their specific requirements. A separate breeding tank with soft, slightly acidic water and fine-leaved plants for egg attachment is essential. During spawning, the male will create a bubble nest, and the female will attach her eggs to the plants. Once the eggs hatch, the fry can be fed with infusoria or small live foods until they are large enough to accept crushed flakes.

In conclusion, Peacock Gobies are stunning and captivating fish that can add a touch of elegance to your aquarium. With their radiant colors and engaging behaviors, they are sure to become a focal point of your aquatic setup. By providing them with a suitable habitat, proper nutrition, and compatible tank mates, you can enjoy the beauty and charm of Peacock Gobies in your own aquatic sanctuary.
