Carp

The Carp (コイ, Koi) is the main member of the carp family. It is a very common river fish, almost as common as the black bass. It, being so common, sells for a measly 300 Bells. The fish can be found all the time. When placed in the museum, the fish appears in the tank on the right in City Folk, but it appears in the first tank in Wild World. It is probably one of the most widespread freshwater fish in the.

Donating to the Museum
As with all fish and bugs in the, the carp can be donated to the museum by talking to Blathers, the curator. During the donation, Blathers will tell the player a little bit about the fish.

In Animal Crossing
When the player donates a carp, Blathers will say this about it before thanking the player for his/her donation:

"Even run-of-the-mill, common fish are valuable resources, you see. All part of the grand tapestry, wot! We will take excellent care of this fellow, oh yes. You can rest assured. Excellent care, indeed."

In Wild World
When the player donates a carp, Blathers will say this about it before thanking the player for his/her donation:

"I do believe many people enjoy this fish raw at sushi restaurants... I understand it makes a rather tasty addition to soups and chowders, wot!"

In City Folk
When the player donates a carp, Blathers will say this about it before thanking the player for his/her donation:

"...Hoo, tell me, have you ever had occasion to see the teeth of a carp? They're positioned far back in the mouth and can bite through seashells! I daresay you shouldn't go sticking your finger into a carp's mouth, wot? That is a mighty chomp!"

In New Leaf
After donating a carp to the museum, a sign will display a description of this fish that says this:

"These tough fish have very long life spans, capping out at ages surpassing 100 years. Their whiskers are one of their trademark features, making them relatively easy to identify. They're omnivorous and eat waterweed and bugs by sucking their food into their mouths. They also have teeth in the back of their throats that help break down shellfish for digestion."
