Thanks everyone for your feedback. I didn't like the substrate either. I've removed the substrate and placed a smaller container inside the viv. This one i believe to be much more suitable for a boa this size. it measures about 12"x8" and the substrate i've used is just kitchen towel. I am also wondering about it being a dwarf.. the origional owner paid just £200 (not entirely sure what that is in USD, i think about $300) which included the snake and the viv. I'm thinking it may be a BCI. Heres what the setup looks like now: I will be changing that stupid heat lamp for a red lamp to sit on top of the viv. It will remain on all the time because at the moment, temperature between night and day are extremes for the snake. I cant use the current lamp much because its too powerful.
