Betta

The Betta is a fish introduced in. It can be found in rivers from May to October (in the Northern Hemisphere), and it sells for 2,500 Bells. It appeared in during the Fishing Tourney: Terrarium event alongside Gourami and Crystal Red Shrimp.

Donating to the museum
As with all fish in, the Betta can be donated to the island's museum by talking to Blathers, the curator. He will say the following when given a Betta:

 * "The betta has long fins and beautiful coloring. It is a tropical fish popular in decorative aquariums. They're very territorial and will fight to complete exhaustion, so aquarists must keep them carefully. Rarely do such beauty and violence commingle outside the rowdiest of sunset-viewing parties."

Once donated to the museum, the Betta can be found in the fish tank in the entrance room alongside the Angelfish and the Nibble Fish.

Real-world information
