The Meteor goldfish is a strange-looking variety that has been developed by specialist breeders of fancy goldfish. It has no tail fin or tail. Its other fins are elongated, and it can swim surprisingly well despite having no caudal fin.
Because no photographs of the breed appear to exist, the Bristol Aquarists' Society has suggested that the meteor goldfish may simply be a rumor. It has been speculated to be related to the Egg-fish.
