This was sold to me as Holothele longipes when it was 2nd instar. Now that its grown a bit it doesnt look like the others I've seen at this size. It looks more like a Haplopelma or Cyriopagopus to me. Obviously I understand it cant be identified at this size.
Can anyone rule out it being heterot
Luckily Ive had a schematic in mind for these long before today. Top left has a hollow half-pipe bark if it wants to utilise that instead of making a tube, top right has a plant stem mimic to build a proper tube against and bottom right bark piece easily allows water to be added from the bottom
