🐠 Pygmy Yellowtail Angelfish (Centropyge flavicauda)
A Deep Blue-to-Black Body Contrasted by a Bright White-Yellow Tail • One of the Smallest True Angelfish • A Striking, Understated Nano Pick
 
📋 The Pygmy Yellowtail Angelfish, also known as the Royal Blue Pygmy Angelfish or Whitetail Pygmy Angelfish, has a striking, understated look: a deep blue-to-almost-black body contrasted against a bright white-to-yellow tail, with fine blue edging along the anal fin. Juveniles typically show more blue-brown tones with the same yellow tail.
It comes from a wide swath of the Indo-Pacific, from East Africa across to Hawaii, Johnston Atoll, and the Tuamotu Islands, one of the smallest members of the entire Centropyge genus, rarely exceeding 5cm even as an adult. Every Pygmy Yellowtail Angelfish we ship is feeding well.
It's reef safe with caution, and benefits from a consistent, varied diet, since an underfed specimen is more likely to nip at stony and soft coral polyps and clam mantles. It's territorial toward other dwarf angelfish and can be surprisingly assertive toward docile tankmates despite its tiny size, so thoughtful tankmate selection matters. It reaches up to 5cm, so a 115L tank suits it well.
