Advertisement I took pictures of a couple of my 2nd instar Uradacus yaschenkoi. I collected them myself from the Murray Mallee region in South Australia. I have been keeping four in a 14" tank for the last 8 months without incident. They get together regularly for little meetings and often 2 share a burrow. They're always swapping burrows and roaming around. Most of the Mallee is compacted coarse red sand , and I found many yasch holes in those areas , but these were found in fine white loose sand so that's what I keep them on, but my other yasch are kept on coarse red sand.
