I have heard that Meraukes tend to be the largest species/localities of BTS - reaching 26-30".

I have seen several BTS care guides videos on Youtube - so I am aware of the basics. Northern & most Australian species tend to prefer humidity levels similar to normal house levels (35-50% range), while the Indonesian localities all seem to prefer humidity in the 60-80% range.

In terms of caging - I am thinking either using my 40 gallon terrarium (36"x18"x16") - If I get a juvenile - then upgrading to the cage once the BTS reaches a year old. If I get a yearling or a subadult - then I will like go with a custom built 4'x2' PVC cage.
