The Bitterling is found in the ponds.
The Bitterling can be donated to the museum. Upon doing so, the following text is given by Blathers:
"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."
Upon catching the fish, the player will say the following:
"I caught a bitterling! What's it so bitter about?"
