Buy Atheris Chlorechis(Bush Viper) Snake Venom/gram
(FREEZE DRIED) SNAKE VENOM
While considered mildly venomous at one time, it has since been proven that Atheris bites in general are serious bites. There is no antivenin manufactured specifically for the species, but it has been reported that Echis polyvalent has been effective in treating bites of other Atheris species.
Overall, the Usambara Eyelash Viper is an impressive specimen and I have heard of a few reptile keepers that have had them in captivity for a number of years now without any issues. That being said, it seems they are still a challenge to breed and there is very little information about their cycling period for breeding. Being an African species I would suggest cycling them in a similar way to other Atheris species by providing them with a period of cooler night time drops not colder than 15°C. In conclusion, if you are fan of arboreal vipers the Usamabara Eyelash Viper should definitely be at the top of your list!
