- "I got a pop-eyed goldfish! It should have eaten its spinach!"
The Pop-Eyed Goldfish, Carassius auratus, is a rare river fish found between the hours of 9am and 4pm, year-round. Like the Goldfish, when placed in your house, it appears in a bowl instead of a fish tank. It sells for 1,300 Bells.
An information board in the aquarium will provide information about this fish.
"They're known for their protruding eyes, as the name indicates, but this feature is actually a detriment. Their vision is quite poor, to the point that they will swim past food and frequently bump into things. They are a type of goldfish and get their distinguishing eye pop about two months after birth."
In real life
Carassius auratus, the Goldfish, a close relative to the Crucian Carp, has been domestically bred into an array of different shapes, sizes and colours. The Popeyed Goldfish breed is a harmless fish that once released lives in slow-flowing ponds, ditches, rivers, and lakes. It is a specially bred type of Goldfish with large, protruding eyes, which to the surprise of some gives it poor eyesight as a result of heavy inbreeding. In the market and aquarium the black variety are frequently known as Black Moor or Telescope Goldfish, and in Japan itself it is called Demekin.
All Goldfish, being in the genus Carassius, share a relation with the more commonplace Carp and Koi. It feeds off of small insects, crustaceans, and plants. In China, it is called the dragon-eye. The species name "auratus" refers to the natural gold-scaled form that can be found in this species.
Popeyed Goldfish are known for having three different types of eyes depending on its ancestry.
