The celestial is rare in UK, being a novelty fish here, but it is popular in China and USA; they are very hard work to breed to the standard. They need to be kept in tanks free of entanglements and without strong overhead lighting; given these conditions, they lead perfectly normal lives.

Celestials first appeared around 1870. In Japan the celestial is called the demeranchu.


The celestial standard is as follows:

The fish should be bright and alert. The body should be medium length with smooth contours and no sign of a dorsal fin. The caudal fin should be well divided, forked and held above the horizontal. The eyes should be well matched, looking upwards and well developed.

Metallic fish may be self-coloured (red, orange, yellow, blue, brown or black) or variegated (any combination of red, orange, yellow, blue, brown, black and white) in a pleasing pattern similar on each side. Quality fish will have high colour intensity and metallic shine extending into the fins.

Calico fish should have a blue background with patches of violet, red, orange, yellow, brown and white, spotted with black. Quality fish should have a high intensity of colour evenly distributed over the body, with colour, especially black, extending into the fins.

Ideal profiles are illustrated below:

This is a recent good example of the type, with good body depth, although the tail lobes are somewhat long for the British standard. Shown at BAS 2008.

This fish was shown at BAS 2001 and has the typical long-lobed, Far Eastern tail.

Adult celestial, red metallic, 2003 - selective breeding in action...

This fish was shown in 2003 and illustrates selective breeding in action - it is from the same stock as the 2001 exhibit (above) and, over the two intervening years, the breeder has developed the shorter, wider tail lobes (fantail-type) of the standard and has improved (deepened) the red colouration.
