Minor Tetra

The minor tetra (Hyphessobrycon minor) is a small fish closely resembling its relative the serpae tetra.


Origin

The minor tetra is native to the Essequibo River in Guyana in South America, while the serpae tetra is native to the Rivers Amazon and Paraguay, so in the wild these two very similar species appear to be separate, so they would not interbreed.

Water conditions

The minor tetra is suited to a pH between 6.5 and 7.6. This means that it is more adapted to slightly alkaline water than most South American tetras. It is also another difference between the minor tetra and the serpae tetra. A temperature of between 23 degrees C (73 degrees F) and 27 degrees C (81 degrees F) is suitable for maintenance although this fish will survive a little outside this range. Moderate hardness is not a problem.
