No problem with that, it is a good idea. I have been trying to do that so I don't start threads that could otherwise be linked. What temperature are you incubating them at?
The male robertmertensi are much more bold, in my experience. There seems to be a greater disparity between male and female in regards to this. One of my females was fairly bold, but has been very reclusive since I moved that pair into a new enclosure over six months ago! They have still produced for me, but she is really shy now. Your video of the borbonica was pretty cool!
