Guppy

The Guppy is a rare freshwater fish found in the river during the months of April through to November between 9am to 4pm. It tends to be rare 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, which is equal to that of the Goldfish and Popeyed Goldfish. Its shadow size is tiny in all games.

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.

Further Information
The guppy, also called the millionfish due to its rapid breeding, is one of the most popular freshwater aquarium fish species in the world. It is native to Barbados, Brazil, Guyana, Netherlands Antilles, Trinidad and Tobago, the US Virgin Islands and Venezuela.

The fish was discovered in 1866 in Trinidad by Robert John Lechmere Guppy, hence the name, and the latin name was originally put forward by Albert Günther as Girardinus guppii. However it had already been described under P. reticulata, and G. guppii has become a Junior synonym, but the common name still continues to dedicate its finder. Poeciliata is from "Poecile" referring to its small size, and reticulata comes from "Reticulate" referring to its vast network of patterns.

Guppies have 23 pairs of chromosomes which is equal to a human's.
