Bubble Eye and Celestial

Bubble-eye and Celestial


Both of these fish have a similar mutation that forces the eyes upward. The Bubble-eye is further adorned with water filled bubbles that are the result of vesicular secretions. In North America the Celestial is fairly rare, while the Bubble-eye is fairly common. Both breeds originated in China, but is typically imported from other lands also. The Bubble-eye and Celestial are both bred in North America.

Breed Development

The following details are typical of both fish types;

  1. Fins are matched, tail can be quite long on the Bubble-eye and are typically shorter on the Celestial.

  2. Tails on both varieties are split a minimum of 35%, fused tails are disqualified.

  3. Eyes and bubbles must be matched. It is possible to have more than one bubble on both sides of the head, but they have to be matched to exhibit.

  4. Scales should be regular, symmetric and in rows.

  5. Back should have a slight curve, but not humped.

  6. Fish should be able to swim without flipping over, but a waddle because of bubble weight is acceptable.

  7. Calicoes are preferred to have blue in their pattern.

  8. The best fish have bubbles that do not have veins showing or at least they are not prominent.
