Native to the slow-moving, densely vegetated streams and pools of Papua New Guinea and surrounding Pacific Islands, this compact, jewel-like fish is prized for its extraordinary colouration — a vivid blue-grey body peppered with iridescent blue and red spots, bold red and yellow fin accents, and a distinctive black spot at the base of the tail that gives the species its Latin name. Males develop a characteristic nuchal hump on the forehead as they mature, adding a further point of distinction between the sexes.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eDespite technically being a goby, the Peacock Gudgeon behaves more like a dwarf cichlid in the aquarium — establishing small territories, displaying fascinating spawning and parental behaviour, and interacting with its environment in an alert, intelligent way that makes it endlessly engaging to observe. It is one of those rare fish that genuinely rewards patient, attentive keeping.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePeacock Gudgeon Care Guide\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eCare at a Glance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eScientific name: Tateurndina ocellicauda\u003c\/li\u003e\n\u003cli\u003eAlso known as: Peacock Gudgeon, Peacock Goby, Eyespot Gudgeon\u003c\/li\u003e\n\u003cli\u003eOrigin: Papua New Guinea and surrounding Pacific Islands\u003c\/li\u003e\n\u003cli\u003eAdult size: up to 3 inches (7.5 cm) — males slightly larger with a pronounced forehead hump\u003c\/li\u003e\n\u003cli\u003eMinimum tank size: 20 gallons — longer tanks preferred\u003c\/li\u003e\n\u003cli\u003eTemperature: 72–79°F (22–26°C)\u003c\/li\u003e\n\u003cli\u003epH: 6.0–7.8\u003c\/li\u003e\n\u003cli\u003eHardness: soft to moderately hard water\u003c\/li\u003e\n\u003cli\u003eBest kept in pairs or small groups with more females than males\u003c\/li\u003e\n\u003cli\u003eLifespan: 4–5 years with good care\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePeacock Gudgeon Tank Setup\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eA well-planted aquarium with gentle filtration, plenty of hiding spots, and subdued lighting suits Peacock Gudgeons perfectly. Dense planting along the sides and background, driftwood, smooth rocks, and caves or ceramic tubes provide both shelter and potential spawning sites. Java Moss and similar fine-leaved plants are particularly appreciated. A sponge filter is ideal — it keeps flow gentle, poses no risk to fry, and provides additional biofilm grazing surfaces. Males will establish small territories and display to one another, so provide sufficient visual barriers in tanks with multiple males.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFeeding Your Peacock Gudgeons\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eCarnivorous predators with a healthy appetite. They readily accept high quality pellets and flake foods, but truly thrive with regular supplements of frozen or live foods such as brine shrimp, daphnia, bloodworm, and micro worms. A varied, protein-rich diet brings out the full intensity of their iridescent colouration and encourages spawning behaviour.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eBreeding Peacock Gudgeons\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eOne of the most rewarding aspects of keeping Peacock Gudgeons is their willingness to breed in the home aquarium. The male selects a cave, ceramic tube, or sheltered spawning site and entices the female to deposit eggs inside. He then guards and tends the eggs exclusively until they hatch — a fascinating behaviour to observe. Fry are small but relatively straightforward to raise on baby brine shrimp and micro worms in a dedicated grow-out tank.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePeacock Gudgeon Tank Mates\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eTank mate selection requires some thought with Peacock Gudgeons — they are carnivorous predators that will eat anything small enough to fit in their mouth, including shrimp and small fish.\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eMedium-sized peaceful community fish such as tetras, barbs, and danios of similar or larger size\u003c\/li\u003e\n\u003cli\u003ePeaceful gouramis and similarly sized community fish\u003c\/li\u003e\n\u003cli\u003eLarger corydoras and peaceful bottom dwellers\u003c\/li\u003e\n\u003cli\u003eAvoid shrimp of any size — they will be eaten\u003c\/li\u003e\n\u003cli\u003eAvoid small fish such as nano tetras, chili rasboras, small danios, and juvenile fish — these will be viewed as prey\u003c\/li\u003e\n\u003cli\u003eAvoid large or aggressive fish that will intimidate or bully them\u003c\/li\u003e\n\u003cli\u003eAvoid fin-nipping species\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Poseidon Aquatics And Plants","offers":[{"title":"Default Title","offer_id":48646138331358,"sku":null,"price":19.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/4768\/4574\/files\/Photo_c76bf674-ca83-49a4-aa92-26174c534b16.png?v=1741201181","url":"https:\/\/poseidonaquaticsandplants.com\/products\/peacock-gudgeon","provider":"Poseidon Aquatics And Plants","version":"1.0","type":"link"}
