Well, I checked some local suppliers and one said they could get me "charal de burro" which they claimed is a type of FHM. (Sorry, don't really belive them.)
They did have on hand the following carp variants, they said these were the most resiliant they have on hand. (Shown below)
I have seen some minnows/small fish in another location with similar water supply. I am going to try and snag a picture of them...that takes a lot more work. We'll see.
