Can anyone point men in the direction of a site that list species by location? Finding limited info in google searches-
Looking for fish found in Rio auto or Rio calima
Here is a list of Colombian freshwater species. They are not listed by specific drainages, but may be a good resource to make a list for further research. https://fish.mongabay.com/data/Colombia.htm
Edit: I just noticed the list was generated by fishbase.org which was already mentioned by
