What is peacock gudgeon?

The peacock gudgeon, scientifically known as Tateurndina ocellicauda, is a small freshwater fish native to Papua New Guinea. They are popular among aquarium enthusiasts for their vibrant colors and interesting behaviors.

Adult peacock gudgeons typically grow to about 2-3 inches in length and have a slender, elongated body with long fins. The males are more brightly colored than the females, with blue and red markings on their fins and a yellow-orange body. The females are generally duller in coloration.

Peacock gudgeons are peaceful fish that can be kept in community tanks but should not be housed with aggressive or overly active tank mates. They prefer planted tanks with plenty of hiding spots and open swimming areas. They are best kept in groups of 4-6 individuals, with a ratio of one male to multiple females to prevent aggression.

In terms of diet, peacock gudgeons are omnivores and will eat a variety of foods including small live or frozen foods, as well as high-quality flake or pellet foods. They should be fed multiple times a day in small amounts.

Breeding peacock gudgeons can be challenging, as they are cave spawners and require specific water conditions and hiding spots to successfully breed. The females will deposit their eggs in a cave or crevice, and the male will guard the eggs until they hatch. The fry are relatively small and should be fed infusoria or liquid fry food until they are large enough to eat bigger foods.

Overall, peacock gudgeons are a beautiful and interesting addition to a peaceful community aquarium, but they do require specific care and attention to thrive and breed successfully.
