Gar

The rare Gar (ガー, Gā) acts as a nighttime counterpart to the Giant Snakehead. It sells for 6,000 Bells, the only fish that does, and is approximately two and a quarter meters long. It appears in summer from 4:00 PM to 9:00 AM. It is also the most expensive lake fish.

Donating to the museum
When placed in the museum, the Gar shares a tank with the Arapaima, the middle tank in and the middle-right tank in. Until, Blathers makes a small speech about the donated Gar.

In
", if you plan to raise a Gar at home, I have some crucial advice. You must be very careful not to overfeed it! These brutes grow much faster than you might suspect, eh wot? Before you know it, it could be bigger than you can handle! The horror!"

Blathers will say this when given the long fish:

"Hoo, I daresay you've really fished a winner this time, my dear owlet! Gar can grow to massive sizes--up to 120 inches! Let's hope this new addition to our museum can grow to an equally enormous size..."

"Their long faces and large mouths make them look like alligators. Some can grow up to three yards. They are ancient fish that haven't changed since they first appeared millions of years ago. They breathe not only through gills, but also by sticking their mouths above the surface of the water. Gar eggs are poisonous, so people all over the world are advised to not eat them--no exceptions."

In
"Hoo hoo! So you have snagged a gar. Did you know this beastly fish can grow up to nine feet long? Indeed, the gar is a remnant of times long past--a living fossil, of you will. It not only has sharp teeth and armor-like scales...it has the ability to take breaths of air as well! Ah, to look upon this unusual fish is to get a glimpse of our prehistoric past."

Further information
This fish can be caught up to about 4 meters (12 ft) in length. Its scales are diamond-shaped and are sometimes used for jewelery. It appears in North America, particularly the United States of America.
