Peacock Gudgeon 3cm

The Peacock Gudgeon (Tateurndina ocellicauda) is a jewel of the freshwater hobby — a small, brilliantly coloured gudgeon native to Papua New Guinea. Males display vivid blue, red, and yellow patterning with a distinctive eye-spot on the tail, making them one of the most visually striking nano fish available. Despite their exotic appearance, they are surprisingly hardy and peaceful, making them an excellent choice for planted nano and community aquariums. Available at 3cm.
