Peacock Gudgeon

The Peacock Gudgeon combines a pale blue body, red markings, yellow fin accents, and a dark tail-base spot in a compact freshwater fish. It is an attractive choice for a sheltered planted aquarium, where calm surroundings allow its colors and social displays to stand out.

Fish details

• Scientific name: Tateurndina ocellicauda
• Size offered: 3 cm
• Adult size: Approximately 5–8 cm
• Origin: Papua New Guinea
• Water type: Freshwater
• Temperament: Usually peaceful; males may defend a cave or breeding territory

Recommended aquarium conditions

• Aquarium: 20 US gallons or larger for a planted community or small group

Provide plants, wood, and several small caves or smooth tubes. Shelters should be distributed so one fish cannot monopolize all of them. Keep some open space for feeding and maintain a close-fitting lid. A bare, exposed tank often makes this species less confident.

Diet and feeding

Offer small frozen or live foods such as brine shrimp, daphnia, and bloodworms, alongside appropriately sized prepared foods if accepted. Watch shy fish during feeding; peaceful behavior does not mean they can compete successfully with every fast-moving community species.

Compatibility and care

Choose small, peaceful companions with similar water requirements and avoid large predators or persistent fin nippers. Very small shrimp and fry can be eaten. Pairs or small groups can work when there is enough cover and floor space, but monitor territorial displays around caves. Keep water conditions stable and perform regular maintenance. Mature males and females differ in shape and color, so the reference photograph does not guarantee the sex or appearance of each animal.
