Peacock Goby (Tateurndina ocellicauda)
The Peacock Goby, scientifically known as Tateurndina ocellicauda, is a captivating freshwater fish native to the rivers and swamps of Papua New Guinea and parts of Indonesia. These small, colorful fish are a favorite among aquarists due to their striking appearance and engaging behavior.
Appearance
Peacock Gobies are renowned for their vibrant colors and unique patterns. Males are particularly eye-catching, displaying a dazzling array of iridescent hues, including blue, green, and yellow, complemented by distinctive eye spots on their dorsal fins. They typically reach lengths of about 3 to 4 inches (7.5 to 10 cm). Females are smaller and less colorful but still retain an appealing appearance. Their elongated bodies and large, expressive eyes contribute to their charm.
Habitat and Behavior
In their natural habitat, Peacock Gobies inhabit slow-moving waters, swamps, and floodplains, often found among dense vegetation and substrate. They are generally peaceful and social fish that thrive in groups. Males can be territorial, especially during breeding, but they usually coexist well with other species in a community tank. Their active nature and interesting behaviors, such as darting and displaying during courtship, make them a delight to observe.
Diet
Peacock Gobies are omnivorous and require a varied diet to thrive. In captivity, they should be fed high-quality flakes or pellets, supplemented with live or frozen foods such as brine shrimp, daphnia, and bloodworms. They also appreciate small vegetable matter, like spirulina. Providing a balanced diet is essential for their health and vibrant coloration.
Tank Requirements
To successfully keep Peacock Gobies, a minimum tank size of 20 gallons is recommended. They prefer slightly acidic to neutral water conditions, with a pH range of 6.0 to 7.5 and a temperature between 75°F and 82°F (24°C to 28°C). A well-planted aquarium with plenty of hiding spots, such as rocks, driftwood, and dense vegetation, will help replicate their natural habitat and create a comfortable environment.
Compatibility
Peacock Gobies are generally peaceful and can coexist with a variety of community fish. They do well with other small, non-aggressive species, including tetras, rasboras, and small catfish. However, care should be taken with larger or more aggressive fish, as they may pose a threat to the gobies. Providing ample space and hiding spots will help ensure a harmonious tank environment.
Conclusion
The Peacock Goby (Tateurndina ocellicauda) is a stunning and engaging addition to any freshwater aquarium. With proper care, a suitable environment, and a varied diet, these fish can thrive and add a splash of color and activity to your aquatic setup. Their unique appearance and lively behavior make them a favorite among both novice and experienced aquarists, enhancing the overall beauty and dynamics of the aquarium landscape.
