I have been toying with the idea of a natural vivarium for a while so finally did it and here is a pic of the first one.
Also using a bio-active substrate - so far so good and it seems as if the Bush Viper is happy!
Lets see if the Ficus Bonsai will survive.
Also "natured" up the Kanburi Viper tank.
I know the lighting may not be 100% but that will change as soon as I have finished the rack for the Exo Terra tanks.
Next on the list is the Armenian Viper tank.
