...I currently have a male Bothriechis nigrovridis and a much larger male B. lateralis housed together. THey aren't aggressive toward one another and sometimes are coiled together in the branches.

I only did this, because the female lateralis will only take live mice, so I had to remove the male so he wouldn't eat the live feeders. The male is going out on breeding loan soon so, it's only a temeporary arrangement.
