Petitella bleheri is a species of characin found in Amazon Basin in Brazil and Peru. One of three species called rummy-nose tetra, but is also called firehead tetra according to FishBase. Reaching a standard length of 2 in (5 cm) it is a common species found in the aquarium trade although often potentially hybridised with the other collective rummy-nose tetra species Petitella rhodostomus and Petitella georgiae; the false rummy-nose tetra.

Taxonomy and systematics

The specific name, bleheri, honours the species’ discoverer, Heiko Bleher.[3]

The genome was fully sequenced in 2015, by standard PCR, and found to be 17,021 base pairs long.[4]

Distribution

This species is found in the Rio Negro and Rio Meta basins.

Diet

Omnivorous and will accept just about anything offered. Species does have a small mouth so correspondingly sized foods are best. Feed a mixture of dried flakes and granules and small live and frozen foods. A varied diet such as this is essential for the best colour development.
