Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.
Niger Tetra (Arnoldichthys spilopterus) is a fish native to Nigeria. The history of invasiveness is uncertain. There are no confirmed introductions of A. spilopterus in the wild. It was introduced to China for aquaculture. There is a record of its introduction to Taiwan, but no information on whether this introduction is within captivity for aquaculture or in the wild. A. spilopterus has been in commercial trade for aquariums for some time (Chapman et al. 1994) but no information on the volume of trade was found. The Climate 6 score was 0.000, low. The climate match does not indicate that there would be suitable habitat for this species within the United States. The certainty of assessment is low. The overall risk assessment category is uncertain.
