Guppy

The Guppy is a rare fish found in the river during the months of April through to November between 9am to 4pm. It is rarer during the month of April, but will become easier to find as the months go on. It sells for 1,300 Bells in Tom Nook's Store. Its shadow size is tiny.

Donating to the Museum
As with all fish in the, the guppy can be donated to the Museum by talking to Blathers, who will also give a small talk about it.

In Wild World
Blathers will say this when given the fish for donation:

"Many don't know that the guppies with ornate tails are actually the males! Indeed, the females are quite dull...much like Celeste, always stargazing. I really wish she would pay attention to something else on occasion... Ah! I'm terribly sorry! That wasn't what we were talking about, was it?"

In City Folk
Upon donating to the museum in City Folk, Blathers the curator will say;

"Male guppies are known for their colorful, bright scale patterns... But look closer, and you'll see males share a design with their female peers... Indeed, a matching couple! It seems like the pairs are a little shy about their romance and tend to hide it. Simply adorable!

The guppy can be found in the small tank in the bottom-left of the aquarium, with other tiny fish in City Folk.
