Carassius auratus
A butterfly tail with a white body and black on the eyes and fins, named for the panda-like contrast. Its broadly spread tail seen from above and its protruding eyes make it a favourite among butterfly tails.
The panda butterfly tail is the colour form with a white body and black on the eyes and fins. The black-and-white contrast suggests a panda, hence the name; a red-bodied fish with black fins is called a lesser panda instead. The butterfly tail itself is Chinese and reached Japan in the late 1970s, though it is now bred domestically as well. It is shown from above, with the shallow clefts and widely opened lobes of the butterfly caudal, and most individuals carry protruding telescope eyes. Like all butterfly tails it fades readily, and losing the black leaves an all-white fish, so consistent colour-enhancing food is the condition for holding the markings. A still, current-free environment is recommended.

Prepared foods, frozen bloodworms, colour-enhancing food
The breed is enjoyed from above for the spread of its tail, so provide enough light to show the tail outline from the surface. Avoid overly strong light to hold the black, and pair this with colour-enhancing food.
A still tank or a water bowl is recommended so the tail is not damaged. Strong aeration disturbs its swimming and drains its stamina, so keep aeration to a minimum.
It does not suit fast-swimming companions; the usual pairing is with equally slow Chinese breeds such as the celestial eye or bubble eye. Choose tank mates that will not peck its protruding eyes.
If the black fades the fish turns all white and the panda markings are lost. Keep feeding colour-enhancing food and avoid sudden swings in temperature or water quality to slow the change.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
