Peacock Gudgeon Goby

Peacock Gudgeon Goby (Tateurndina ocellicauda)

The Peacock Gudgeon Goby is a vibrantly colored freshwater fish that is cherished for its unique appearance and peaceful temperament. These fish exhibit a stunning combination of iridescent blue, red, and yellow colors, along with striking black markings.

Peacock Gudgeon Gobies are compatible with similarly peaceful tank mates and grow to a moderate size of around 2.5 inches. A group of 6 or more individuals is recommended to observe their interesting social behaviors.

Somewhat territorial towards its own kind, the Peacock Goby can still coexist in community tanks with small, peaceful fish. Ideal companions include other Papua New Guinea species like Popondetta sp. rainbowfish, as well as tetras, rasboras, Corydoras catfish, and virtually any other small, non-aggressive species. Ensure ample tank space if housing them with other territorial species, such as dwarf cichlids.

Peacock Gobies can be maintained in small groups without significant issues. Although they may engage in minor squabbles, these interactions typically involve displaying and flaring, creating an engaging spectacle rather than causing harm. In fact, keeping a group can be more entertaining than housing only a pair.

Peacock Gudgeon Gobies are omnivorous and will accept a variety of live, frozen, and high-quality dry foods. A balanced diet consisting of brine shrimp, daphnia, bloodworms, and quality flakes or pellets will keep them healthy and maintain their vivid colors.

Utilizing a dark substrate and incorporating floating plants will make the fish feel more at ease and enhance their coloration. Although they require numerous hiding spots, Peacock Gudgeon Gobies hide less often and become more active in densely planted aquariums filled with driftwood and caves. Conversely, in bare tanks, they tend to cluster near any available cover and move less throughout the tank.

A minimum aquarium size of 20 gallons is recommended for a pair or 30+ gallons for a group.

While they prefer pristine water conditions, excessive water flow can be detrimental to their well-being. Peacock Gudgeon Gobies prefer slightly acidic to neutral water with a pH of 6.5-7.5, a hardness range of 5-12 dGH, and a temperature between 72-79°F (22-26°C).
