🐠 Golden Dottyback (Pseudochromis fuscus)
Marine Reef-Safe-With-Caution Dottyback • Genuinely Variable Yellow to Brown Body • Genuine Documented Damselfish Mimic • Intermediate Marine Fish
📋 We want to be genuinely upfront about naming: "Golden Dottyback" is a common name shared with another distinct species, Pseudochromis pseudoplesiopinae. This listing refers to Pseudochromis fuscus, also known as the Brown, Musky, or Dusky Dottyback — please ask our team to confirm identification if you're unsure.
📋 The Golden Dottyback has a genuinely variable body colour, ranging from uniformly bright yellow to pinkish, greyish, reddish-brown, or almost black, often with fine blue spots on the scales and a yellow dorsal fin.
Native to a genuinely vast range across the Indo-Pacific, from Sri Lanka to Vanuatu, this species is genuinely the largest member of the Pseudochromis genus, reaching up to 10cm.
A genuinely remarkable, scientifically documented behaviour defines this species: it's a real damselfish mimic, and research has shown its colouration can shift depending on which damselfish species it's mimicking on a given reef, allowing it to approach prey undetected. It's fully carnivorous and genuinely aggressive, particularly toward similarly sized fish, and should be kept singly. It's considered reef safe with caution — it won't harm corals, but genuinely should not be kept with crustaceans or smaller fish it may bully or eat.
