Overview
The Negodagua tetra is a small, active schooling fish for a community tank that runs on the cool side. It is a step up from the easiest fish.
Did you know
The Negodagua tetra has no adipose fin, just like its silvertip relatives. Nearly every other tetra wears that small second fin between the dorsal fin and the tail.
Caring for the Negodagua tetra
Keep Negodagua tetras in a group of six or more, in 15 gal (55 L) or larger. Give them some current, rockwork or wood, and good oxygenation.
They prefer the cool end of the tropical range, at 68 to 79°F (20 to 26°C) with a pH of 6.0 to 7.5. If your room stays temperate, an unheated setup can suit them. They take flake, granules and frozen foods.
They behave much like their cousin, the silvertip tetra. They are active, school tightly and are a little bolder than the average rare tetra. Negodagua tetras are peaceful and safe with community fish.
Good to know
The Negodagua tetra, Hyphessobrycon negodagua, belongs to the family Characidae. Current classification moves it to Hasemania, the genus that includes the silvertip tetra.
In the wild
The Negodagua tetra is endemic to the Paraguacu drainage. It lives in the upper Paraguacu basin, in the Chapada Diamantina highlands of Bahia, Brazil. Its clear, mountain-fed streams run cooler than the Amazon lowlands.
