Black Celestial Eye

The Black Celestial Eye is a solid black variety of the Chinese celestial eye goldfish, known for its eyes that protrude and point straight upward, giving it a striking, almost otherworldly expression. It has no dorsal fin, and its four-lobed tail paired with a slightly elongated body gives it an elegant silhouette. Because its eyes face upward, this goldfish has very little functional eyesight and relies on its sense of smell to find food, which adds to its distinctive charm. Its movements tend to be calm and unhurried, and many individuals have a gentle temperament. Fully grown, it reaches around 20 cm in length and has a strong presence gliding through the water. Because of the extra care it requires, it is generally considered a variety suited to experienced keepers.

About Black Celestial Eye

The Black Celestial Eye is an all-black variety of celestial eye goldfish with upward-facing, protruding eyes and no dorsal fin. It has almost no eyesight, relies on smell to find food, grows to about 20 cm, and suits experienced keepers.

7 things to know before welcoming a Black Celestial Eye

  1. 1Little to No Eyesight

    Because its eyes point straight upward, the Black Celestial Eye can barely rely on sight for finding food, and instead locates it mainly by smell. Dropping food in the same spot and at consistent times each day makes it easier for them to find. Keep in mind that in mixed tanks, they can be at a disadvantage competing for food against sighted goldfish.

  2. 2Choose Tankmates Carefully

    Since it can't rely on sight, the Black Celestial Eye may struggle to get enough food when kept with fast-swimming, food-competitive varieties. Calmer goldfish with a similar swimming pace make better tankmates.

  3. 3Protect the Protruding Eyes

    The upward-pointing eyes are prone to injury if they bump against hard decorations or get caught near filter intakes. Choose smooth, rounded decor and position equipment carefully to help protect their delicate eyes.

  4. 4An Advanced-Level Variety

    The Black Celestial Eye is generally classified as suited to experienced keepers, requiring closer attention to water quality, temperature, and tankmate selection than many other goldfish. It's best suited to those who already have some goldfish-keeping experience.

  5. 5No Dorsal Fin

    The absence of a dorsal fin gives this variety an elegant look, but it can also mean somewhat weaker balance while swimming compared to finned goldfish. Keeping filtration flow gentle helps prevent them from tiring out.

  6. 6Four-Lobed Tail and Elongated Body

    A four-lobed tail combined with a slightly elongated body gives the Black Celestial Eye its distinctive silhouette. Providing a tank with enough open swimming space helps this body shape develop and move well.

  7. 7Prepare the Tank Before Bringing One Home

    Because this goldfish can't rely on sight and its eyes are easily injured, it helps to set up a tank with minimal sharp decor and gentle water flow before bringing one home. Stabilize water quality in advance and avoid sudden temperature swings when introducing them.
