 Just look at that little face... No wonder then, that so many fishkeepers find these little puffers so hard to resist.

Hyphessobrycon klausanni.

A lovely new species of Hyphessobrycon has been described from the Orinoco River basin in Colombia.


Hyphessobrycon klausanni was discovered in upper Guaviare River drainage.

Measuring 2.3cm (SL), the new species was found living in shallow, well-oxygenated streams with clear water flowing over various substrates including rock, sand, gravel and leaf litter, and among aquatic vegetation, tree roots and logs.

Temperature was 25.5–26°C, but pH varied from 6.47–8.7. 

Research leading to the discovery of this new species was partially funded by Mr. Klaus-Peter Lang from Oberhausen, Germany, and the species name is dedicated to and named for his father, Klaus and his mother, Anni.
