Neon tetra

"I caught a neon tetra! I'd better put on some sunglasses!" - City Folk

The neon tetra is a tiny fish found in the river between the months of April and November between 9am and 4pm. In the "Bugs and Fish" window, it says, "A standard in many aquariums, these are easy to raise but hard to breed." It was introduced in City Folk.

Donating to the Museum
Upon donating to the Museum, Blathers will say;

"That metallic blue body! Hoo, that crimson tail! That pristine white belly! ...Now, THIS is what I call a tropical fish! No wonder this fish has the word "neon" in its name, eh wot? One of these should liven up the museum nicely!"

It can be found in the small tank to the left with the Goldfish and Popeyed Goldfish in City Folk.
