[msjinkzd]

this fish came in at abotu 1/8" mixed with some tetras in an import order I did about 3 months ago. Any clue what species it is:

Probably A. cf. pertensis (Lower Negro) - A147, since it came as a contaminant in a box of Paracheirodon simulans. Their ranges overlap in the area above Barcelos, Brazil.
