Nice-looking little Mangrove viper! However, that bedding is bad news for that species. Mangrove vipers live in trees near the waters of mangrove swamps. They need high humidity and lots of perches.
Aspen simply will not work...it will mold, or the snake will shed horribly...probably both. You would do well to switch to cypress mulch or jungle floor mix bedding. You should provide plenty of perches, lots of fake vines and plants to hold water, and mist several times a day.
Here are some pictures of the setup I have for my baby C. purpureomaculatus:
I hope this helps; If you have any more questions, feel free to message me. Good luck with the little one. Be careful- their bites can be lethal, but usually do not kill. However, I've heard that they are one of the more painful bites a keeper can endure.
