### Single-tailed Goldfish[edit]

Goldfishes have been kept in captivity longer than any other fishes, and many varieties developed from the one original species, Carassius auratis, remain popular. This section is devoted to single-tailed varieties - hardy fishes that can over-winter outdoors. Their cultivation is generally limited to developing exaggerated fins and various color strains.

### Twin-tailed Goldfish[edit]

These goldfishes are termed "twintails" because their causal and anal fins hang in double folds. Their aquarium-bred bodies become truncated and egg-shaped, and the ability to swim is gradually impaired as the form changes from the natural streamlined shape. These restrictions mean that twintails are not suited to outdoor ponds. They could not compete in a race for food, nor flee from predators. Their delicate fins may also become congested in inferior water conditions. The maximum size of a twin-tailed goldfish attains depends on the size of the tank in which it is kept.

Koi are ornamental domesticated varieties of the common carp. Despite their long term unsuitability for the indoor aquarium, there are many aquarium-bred strains of the ornamental Koi (Cyprinus carpio) and a selection is shown here. It is customary to view and judge these dish from above, and their colors and patterns have been developed accordingly. Koi originated in east Asia, but strains are now cultivated worldwide.

### Other coldwater cyprinids[edit]

Many fish-keepers' coldwater interests center around Goldfish and Koi, but there are other attractions in this field of the hobby. In spite of their relative obscurity, it is easy to keep different North American fishes, such as shiners and sunfish, as well as bitterlings and some species from Asia.
