Threats

Major Threats
The Caquetá River basin habitat is being polluted by the processing of coca leaves into coca paste and cocaine. Sulphuric acid, ethyl ether, acetone, and kerosene are poured directly into the ground by cocaine processors working in the Caquetá River basin, which is the primary coca growing region. The consequences of this pollution are quickly felt in small rivers where the aquatic life is devastated (Trade and Environment Database 1997).

However, it is unlikely that these threats have impacted across the range sufficiently to be thought of as major threats.
