In Wild World
Blathers will say this as the fish is donated:

"I must say, I've never personally considered eating one of these before. It's so very...goldfishy... No, not particularly tasty-looking, to be sure..."

After donation, the bitterling can be found in the front tank in the first room.

In City Folk
Blathers will say this when handed the small fish:

"It's quite common for enthusiasts to keep bitterlings in the same tank as tropical fish, eh wot? Indeed, once upon a time, this fish was a popular choice for the private fishing ponds of the rich!"

It can be found swimming aound in the middle-left tank in the Aquarium after donation.

In New Leaf
After donating the bitterling, the following information will be displayed by its tank:

''These fish are so small, they can fit their entire body in the palm of your hand. During mating season, the male's belly turns a light orange in order to properly attract a mate. They live in rivers and lakes and deposit eggs in large bivalves where the eggs hatch and live for a while.''

The bitterling can be found in the larger of the two left-hand tanks in the freshwater fish room.
