I and many others are currently still seeking mt meru's so if anyone out there happens to know where we can find them it would have amazing to know. I do know that is it next to impossible to find but any information helps.
This is by far the rarest of the T. jacksonii subspecies in captivity and most difficult to keep and breed. Since Tanzania imposed an export ban on all wildlife 3 years ago, the captive population has diminished considerably. You probably will not find any available unless Tanzania reopens to exports.
