Peacock Gudgeon (Tateurndina ocellicauda) is a compact, jewel-toned freshwater fish prized for its iridescent body and calm, inquisitive demeanor. In a lush, well-planted aquarium, this small jewel glides with a confident, gentle motion, often tucked among leaves and driftwood to create a striking yet peaceful centerpiece in a community setup. Native to Colombia and South America, this species brings subtle shimmer and tranquil activity to a thoughtfully arranged tank.

Store quarantine statement (your advantage)

Quarantine advantage: All fish are quarantined and observed for a minimum of 7 days before entering our main system. This proactive step helps reduce disease risk and provides early detection of health issues, giving you a healthier addition to your tank. We still recommend quarantine after purchase to maximize freshness and ensure a trouble-free transition into your aquarium setup.
